America's Got Talent spawned spin-offs in more than 58 countries. Conceived by the reality television series judge that everyone loves to hate, Simon Cowell, it has taken the world by storm. And in 2007, Simon brought that to his home country with Britain's Got Talent. It's a no-rules talent show that is open to professionals and amateurs of any age. In fact, there have been performers ranging in age from 4 all the way to 92. After Simon's extensive experience in the music industry, you would think he has seen just about everything, but The Chippendoubles' performance is unlike any other. It's packed with about seven surprises. Find out why Simon says, "This was, in a way, one of my favorite acts."
