It's interesting to feel the pressure of having to be outgoing because I think in general as a human being I'm pessimistic and introverted. But it's cool because it's a whole different side of me and I impress myself. Even at times when I think that there's no possible way that I can be engaging I'll suddenly pull it out and impress myself.
I met Prince William at a musical festival and he let me know he was a fan of my music. But the invitation to sing at his wedding reception came completely out of the blue. The fact that Kate and William knew the words to my songs was very touching.
