Hair is also a problem. I remember once, when I was reporting from Beirut at the height of the civil war, someone wrote in to the BBC complaining about my appearance.
For me, with the Blue Man Group, I got asked. It was for the Royal Variety Show, which was something I always wanted to be a part of. I'm really interested in things people don't necessarily expect. I did a pop song, but I did it in my own style.
