It's the fourth round of auditions and we're getting close to narrowing down the field even further but there are still some acts to judge.

I find it incredible how the audience turns so vile against the acts that are rubbish.

Thankfully there is Crew 82. Four guys who manage to make music with nothing but their mouths. Simon says he's never heard anything like it in his life and thought it was that good. Amanda thought it was genius. Piers pays them a huge compliment. It's three yeses so they'll be through to compete in the next round.

If ever there was a brilliant streetdancer, it's 13 year old George. He's absolutely phenomenal for someone his age.

Impressionist Richard Bates is not Simon's cup-o-tea. Simon thinks it was the worst act in Manchester but Amanda and Piers are amused. The audience enjoyed it. He's through much to Simon's protesting.

The judges look like they need a drink so it's lucky that Neil & Neil, the Bar Wizards, are here to perform their professional cocktail routine.

14 year old Cameron is a drummer and has to work hard to convince the judges to put him through despite the fact that the audience seem to really like him.

Tony Laf is a young man who is now looking after his brother's children after his brother died. He's brilliant singing and playing his guitar. He's very good and the judges, the audience and I loved it.
