“The song to the movie that we did, The Graduate. The movie music came out before the single, as I recall. These sessions were produced mainly by Roy Halee, a wonderful music maker, although Paul and Art certainly had a lot of input at the time.

“They started out as folk artists but gradually more instrumentation came into their sound. Electric guitars, drums, electric bass – soon, they were doing more pop songs than folk songs. I didn’t get into the politics of all that. I just played what felt right.

“Working with Paul and Artie was great. Whatever I wanted to try, they loved it. I played on things like The Boxer and so many of their fabulous songs. They let me do anything I wanted. Incredible artists, those two.”
