cheekychops is right. My friend went last year, and auditioned in front of judges, who decide whether or not you make it through to the filming with the famous judges. Interestingly enough, the person who went in front of my mate had an amazing voice (he could hear through the door) and she was turned away. An old guy who had dressed up funny and was a bit of a comedian but admitted to not being able to sing, was put through - i suppose he made good TV viewing. What it does mean tho is that some good talent may get missed in the process.
