Thanks for starting this - I had the thought last night when I heard he had died that his roots were in music, moving to acting later. I read or heard an interview about that fairly recently. In the meantime, a reliable place to find older interviews is on Fresh Air with Terry Gross, where he was a guest several times. (If you search on him he is also the subject of other interviews, such as one with the writers of Little Miss Sunshine.
