As a young man, every bone in my body wanted to pick up a machine gun and kill Germans. And yet I had absolutely no reason to do so. Certainly nobody invited me to do the job. But that's what I felt that I was trained to do. Now no part of my upbringing was militaristic.

My father was in a dance band, and I wanted to do what he did, play the saxophone, but I couldn't blow a note, so he suggested the guitar. Chromatic harmonica was actually my first instrument, and I got very good at it - not quite Stevie Wonder, but very good.

What I took back, because of my exposure to the Jewish music of the 30s and the 40s in my upbringing with my father, was that kind of theatrical songwriting. It was always a part of my character. This desire to make people laugh.

I needed to give back, give back, give back. I felt guilty about my success. I felt uncomfortable about how easily I had been delivered this extraordinary life that I had.
