It's very easy for me to say what success is. I think success is connecting with an audience who understands you and having a dialogue with them. I think success is continuing to push yourself forward creatively and not sort of becoming a caricature of yourself.
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.
