We felt the time was right to open up the boundaries, and say to all of America, regardless of your age, whether you're 2, whether you're 100, regardless of what you believe your talent is - juggling, magic, singing - this is the show you can enter. It's as simple as that.

The biggest shock when I lost it all was the realization that so much of my life had been out of my control. When I started to make the money back, I vowed that it would never happen again. I bought things only when I could afford them. There was no big mortgage, no cars on hire purchase. I remember buying a TR6 sports car for £6,000, and funnily enough it gave me more pleasure than the Porsche ever had.
