The piece by Piers is terrific. Here's the rest of it:
I even wrote their name on a piece of paper as my prediction for who I thought would win when we chose the Top 40 as did Simon.
But when I watched that first audition show go out live on ITV, and began getting an immediate big reaction from friends and family, I texted Simon in Los Angeles and said: Id forgotten how brilliant Susan Boyle was.
Within 24 hours, her clip started to shoot virally around the world.
I began getting emails and texts from America, Australia, Italy and Russia all of them from people I knew, saying they had been reduced to tears watching it.
After three days, Susan had become a global internet sensation.
And she dealt with it with consummate ease.
I watched her appearing on huge American TV programmes such as Larry King Live and the Oprah Winfrey Show, and she was just the same Susan I remember from Glasgow.
She laughed, she sang, she pulled faces, she danced a bit, she had fun.
She didnt take herself too seriously.
And she never once showed any sign of discomfort at all the attention.
For week after week, the Susan Boyle phenomenon grew bigger and bigger.
It was one of the most extraordinary things Ive ever seen.
To watch someone go from complete anonymity to international superstardom so fast was just astonishing. But slightly scary, too.
I remember Simon saying after three weeks or so: This is all getting out of control, we need to calm it down.
Concerned: Even Simon Cowell, who is known for his tough image and brutal putdowns of contestants, was worried about the impact on Susan
He was concerned then about Susans bubble bursting as fast it blew up, that people might get bored with her before the live finals.
And he was also concerned about the effect of all the attention on Susan herself.
On his advice, Susan curtailed the number of interviews she was doing, and focused on rehearsing for her next performance on the show.
But the mania continued unabated, and her legend grew by the day: 100million hits on Youtube, 150million, 200million.
Demi Moore even started backing her on Twitter.
It was insane.
Susan Boyle was downloaded more times in a month than Barack Obama, Britney Spears and David Beckham put together.
Shes had, to date, more internet hits than Mandela, Churchill, JFK and Hitler combined.
One afternoon, Amanda joined Ant and Dec in my London flat to do a series of interviews for American television.
We were all united in our shock at the Susan phenomenon.
I cant believe this, said Amanda.
Its ridiculous, agreed Ant.
Unbelievable, whistled Dec.
I laughed. Just think, you three have been trying to crack America for 30 years between you, and shes done it in four weeks.
The next time I saw Susan was on the day of her semi-final two weeks ago.
I came out of my dressing room at the Fountain Studios in Wembley to find her sitting outside, waiting to do her dress rehearsal.
Susan grinned broadly when she saw me. How you feeling? I asked.
OK, OK, she said.
Nervous?
Yes!
She was shaking a bit, but then so were all the contestants.
For amateurs to perform live on a show getting up to 20million viewers is nerve-racking.
The difference with Susan was that until then she had exuded remarkable confidence.
Now, suddenly, I could tell that the pressure was finally beginning to get to her.
She had been the red-hot favourite to win for seven weeks now, which is a lifetime in reality television.
And I think it had slowly dawned on her that virtually the whole world was going to be watching her sing that night, and there was little chance of her ever being able to live up to the magic of that initial audition tape, however well she sang.
Live shows can be brutal, unforgiving things.
Nerves: Susan displayed the initial signs of stage fright at the semi-final but but persevered after missing the first note
Theyre also the greatest test of potential future stars.
Ive seen many talented auditionees shine and fall at this stage of the contest.
Its what makes it so dramatic, exciting, unpredictable and emotional.
When Susan walked out on stage, she looked like a frightened rabbit, and my heart went out to her.
I, too, felt incredibly tense, knowing the size of the likely global audience watching our every move that night, and I was just a judge.
God only knows how Susan, the most famous woman on the planet, was feeling.
Then she began to sing, and missed her very first note. I froze.
Oh God, were we about to see her self-implode on stage?
No, we were not. Susan simply grabbed her diaphragm, took a deep breath and burst into the next few notes with incredible power.
It was a defining moment for me.
The moment when I realised that Susan could hack live performing.
Her rendition of Memory, ironically, was perhaps not quite as memorable as I Dreamed A Dream, but it was good enough to prove that she was not a one-hit wonder, a flash-in-the-pan.
Cracking up: Susan manages a final wiggle despite losing to Diversity
When she heard shed won the public vote, she danced wildly again on stage, pure delight radiating from her face.
This is for you, Piersy baby! she shrieked, amusingly, offering me a very special wiggle. (Shed admitted a few times by now that she had a bit of a crush on me.)
A few minutes later, I was walking back to my dressing room when she spied me, ran down the steps, jumped into my arms and planted a big smacker on my lips.
Ive been kissed now, havent I, Piersy baby! she laughed.
You certainly have, I laughed. You were brilliant out there.
Thank you. I enjoyed it.
And I could see she had. She was ecstatic.
But that was the last time I saw her that way.
From the following day, some of the media and public attitude towards Susan turned negative.
She was scorned for her eccentric behaviour on stage, her apparent lack of humility and the fact she missed a few notes in her performance.
There were reports of her having blazing rows with strangers (who turned out to be journalists) in hotel bars, and of shouting at the TV screen when she saw me praising Shaheen Jafargholi on the second semi-final (she furiously denied this to me).
The headlines over the next few days were strident: BOYLING POINT, SUSANS CRACKING UP!
And they had a huge impact on her.
Until this point, Susan had basked entirely in the positive glow of fame.
Now, suddenly, the mood had changed, and she didnt know how to deal with it.
Im not going to be a rank hypocrite and lambast the media for this mini-backlash.
I was a tabloid editor for 11 years and would have almost certainly pursued the Susan Boyle story with just the same enthusiasm and aggression as my former colleagues were doing now.
I understand, and broadly agree with, the argument that she had voluntarily entered the competition, had courted the worlds media, and therefore had no right to complain.
All that is true.
But she was still entitled to feel upset and angry about it.
Shed already had to put up with being dubbed Hairy Angel and SuBo as if she was some Japanese wrestler, mocked relentlessly for her looks and fashion sense and ridiculed for never being kissed.
Now she was being written off as a not-very-good singer, too, by some of the very same people who had until very recently lauded her to the hilltops.
Celebrities joined in the Boyle-baiting.
Lily Allen sneered that she was overrated, and Craig Revel Horwood (the least known judge on Strictly Come Dancing) said he wanted to smash the TV screen when he watched her in the semi-final.
And with every gratuitous insult, so Susans self-confidence diminished.
By Wednesday, she was in a bit of state.
So much so that I made a public plea for everyone to back off after she threatened to leave the show altogether.
I spoke to her at length on the phone, and she said shed been horrified by the turning of the tide in the Press coverage.
Why are they doing this to me? You used to be an editor, tell me?
Because youre the hottest story in the world, I said. And Im afraid this goes with the territory.
She sounded close to tears.
I was sick last night, and I cant sleep, she said.
I wish theyd just leave me alone.
Thats not going to happen, Susan, and it shouldnt happen.
'You entered this show to be a professional singer, and everyone who does that has to accept that the media will be interested in their story if they do well.
'Theres only one way to shut them all up, and thats to absolutely nail it in the final.
'Kill them with your talent.
There was a pause.
Id better show them all then!
Thats the spirit, Susan.
'My advice is dont read the papers, dont watch TV, just stay calm, keep away from all the mayhem if you can, and concentrate on getting that final performance right.
Ill try, but its not easy. Its everywhere, I cant get away from it.
It is, but there are only a few days left.
'Just focus on your final performance, because in the end that is all that matters now.
She laughed. Ive been practising a lot.
Good! I said.
At this stage, let me explain what goes on behind the scenes on Britains Got Talent.
The contestants are not just left to their own devices.
There is a huge support staff of people to advise them, and they are incredibly experienced in this kind of show.
The team on BGT also do X Factor, so they have had years of dealing with the highs and lows of being a contestant.
From my first-hand experience, this team are remarkably kind, patient and sympathetic.
They all know how nerve-racking it is, how difficult to suddenly find yourself thrust into the public eye, however much you want to be thrusted in the first place.
Simon, despite his tough-guy reputation, wants the show to be essentially uplifting and positive, not some kind of unforgiving Roman amphitheatre.
We want people to have a good time, both as contestants and as viewers, he told me.
Britains Got Talent works best when its a warm celebration of British talent and eccentricity, not when it resembles a bearpit.
That doesnt mean we cant all have a good laugh at the daft, deluded acts, or mock the occasional complete idiots who grace our stage.
But it does mean that everyone working on the show knows there are limits, and that they take those limits very seriously.
Background checks, for instance, are done on every act that appears.
Everyone knew Susan was an exceptional case, the most talked-about contestant in the history of talent shows.
And she was repeatedly asked if she felt OK about continuing in the show.
Yes, she always replied. I wouldnt have entered otherwise.
To try to make things easier for her, various close friends and family were flown down from Scotland to offer support and this definitely helped.
On the day of the final, I had another conversation with Susan on the phone.
You OK?
Not really, she said. Ive not had a good nights sleep all week, I havent been eating much, and Im really stressed out.
Youve got your chance to show everyone what you can do tonight.
'This is it, Susan. This is your moment to have the last laugh.
She laughed. I dont feel much like laughing. Theres so much pressure, I dont want to let anyone down.
You wont. You have inspired millions of people around the world with your singing, and you mustnt let a few silly headlines ruin it for you.
'Youve enjoyed the show havent you?
Oh yes, of course. Ive been living my dream.
I believed her, but was still worried for her.
You going to be OK tonight?
She didnt hesitate.
Yes.
Two hours later, I found her waiting in the corridor to rehearse.
She was sitting next to the grandfather from fellow BGT hopefuls, 2 Grand.
Both seemed quite awed by the occasion, which was no surprise given the enormity of the ratings.
Look after each other, I said, and they smiled.
Then I gave Susan a quick hug. Go out there and do what you do best tonight.
I will, she said.
Later that night, Susan walked on to the stage and unleashed a magnificent new version of I Dreamed A Dream.
I was staggered by how confidently she sang.
After the extraordinary rollercoaster shed been through, I genuinely feared it might all end in tears at the final hurdle, that she might crack under the maelstrom of attention and expectation.
Face of disappointment: Susan appeared to take defeat to Diversity well on the night of the final but checked into the Priory the next day
But she didnt. She nailed it.
To my shock and dismay, though, there were a few boos in the audience when I suggested in my critique that she should win the show.
I realised then that she probably wouldnt win, that the bubble had indeed burst right at the last minute, that the British public as Simon had feared had grown a little bored and irritated by Boyle mania.
In fact, she nearly did win, missing out to the brilliant Diversity by just four per cent of the vote. (Incidentally, Id hate all the ongoing obsession with Susan to detract from this wonderful dance groups achievement. What fantastic role models they are, and what a statement their victory makes about a country supposedly drifting towards the BNP.)
And Susan was fantastically generous and modest in defeat, while reserving the right to do one last wiggle on stage.
Absolutely Flawless: Piers expected the street dance group Flawless to win the show when he first saw their electrifying act
The next day, I was asked to call Susan because she was exhausted and upset.
We spoke for half an hour, and she admitted: Im so tired, I need to get away from all this for a while.
You were brilliant last night, I said.
I didnt win, though. Will I still be able to have a career as a singer?
Of course you will, I replied, truthfully. And remember that your dream was never to win this show, it was to sing professionally.
Thats true, it is. Its all I have ever wanted to do.
She was undeniably jittery and erratic in that conversation.
There were laughter and tears, excitement and sadness.
She had been through an unprecedented two months.
Are you glad you came on the show? I asked.
I am, she said. Even the way I feel now, I am.
Later that night she was admitted voluntarily to the Priory Clinic after seeing some doctors.
She was, they said, completely exhausted.
I felt sad for her, but relieved too.
The Priory is a favoured destination for stressed-out performers.
They know exactly what Susan had been through, and exactly how to treat it.
Her admittance sparked a new media furore, most of which was laughably hypocritical.
As I said before, I dont blame the papers, TV and radio for pursuing the story, or even how they pursued it.
But I do find some of their shameless finger-pointing faintly ridiculous.
I cannot think of a single thing more that anyone could have done for Susan.
Or a single rule change that could be made to protect future contestants from dealing with the unique problems of experiencing the unprecedented worldwide attention she has had.
Susan wanted to be on this show, has no regrets about doing it, is well on the road to a full recovery already and came out of the Priory last week after just a few days.
Now she wishes to pursue her dream of making an album, a disc that I would guess might sell somewhere north of ten million copies given her astounding popularity in America, making her the biggest selling female artist of the next 12 months.
Ive no doubt shell get exhausted again in the future, and occasionally fed up with overly-critical journalists.
And she will, I confidently predict, also grow to loathe all the travelling, sycophancy, paranoia, insecurity and sheer hard work that goes with being a big star these days.
But when people say she should never have entered the show, and was exploited, I say thats nonsense.
Susan had a blast for 90 per cent of the time, and remains a feisty, funny, independent-minded lady with an incredible talent.
Shes not some sort of cruelly exploited simpleton, as a few ill-informed critics seem to think.
Shes a smart-witted person (watch some of her American interviews) with a great sense of humour, but also a bit of a short fuse when it comes to people abusing her.
I guess when youve been bullied at school like she was, and had yobs chuck stones at your house, you grow less tolerant of that kind of behaviour.
Her brother, an intelligent, articulate, sensible man, summed it all up perfectly this week when he said she just needed a good rest, and added that he was mystified by all this over-exaggerated stuff about her learning difficulties.
She did as well academically as the rest of us, he said. She just used to get very nervous before exams.
The Susan Boyle story is not, as some would have it, a modern-day parable of reality TV disaster, the tale of an innocent victim whose life has been ruined by transient fame.
Its the story of how one woman from a Scottish village set the whole world alight with the sheer force of her personality and raw, undiscovered talent.
OK, so she was a bit drained by the end of the whole shebang. Who wouldnt be?
Im so knackered, I feel like checking myself into the Priory as well.
But without Britains Got Talent, Susan Boyle would have probably carried on living alone with her cat in a remote part of Scotland, never knowing if she had what it takes to be a star.
Now she knows the answer. And so does the entire world.
She does.
