So, imagine you're Simon Cowell, and it's the first round of the British version of American Idol, in Cardiff, Wales. This dumpy cell phone store manager with a bad haircut, bad suit, bad teeth and a cleft palate comes on stage and announces that he's going to 'sing opera'. You'd roll your eyes, too - or at least barely stop yourself from visibly doing so.
Then he opens his mouth...
I'm no expert, and not very familiar with the either the form or the specific piece, but it looks to me like he blew a high note at the end there. Can you blame him? That's his life's dream about to smack him full in the face, right there in front of the TV cameras, thousands of people in the audience, one judge whose breath is coming in hitches, and Simon sitting there like he doesn't know what just hit him. I know I wouldn't be able to hold it together that well.
UPDATE: In the least surprising news of the day. He won.
