I came up in the '60s; that was a time when there was a revolution going on in music. Stravinsky had become a twelve-tone composer; even Aaron Copland was writing twelve-tone pieces at that time!
My father would sit and design furniture and cabinets - he was a carpenter and cabinet maker - and I would ask for my own piece of paper and pencil. And when I would say, 'What should I draw?' he would push a cartoon under my nose and say, 'Here, draw this. ' So the cartoon became a kind of focus of attention.
