I don't know why people are so surprised by my live performances. My approach is so simple; every song I sing, every story I tell, every move I make, must move the audience to laughter, tears or inspiration. Otherwise, why should I do it?
Maybe philosophy - I love talking about ideas. Or maybe art history. I was thinking about psychology, then I got really afraid because everybody says it's terribly boring.
It is refreshing to be able to express my views without having to toe a party line. It has got me into trouble on the odd occasion, but I am not going to stop saying what I think.
