I just go into the studio, look at the lyrics for the first time when I put them on the piano, and go. If I haven't got it within 40 minutes, I give up. It's never changed, the thrill has never gone, because I don't know what I'm going to get next.

I had to learn how to function as a human being. And I really enjoyed that process.
