Thanks for that excellent report. Intrigued that some things haven't changed since I saw him in a small room in the sixties - the repertoire was much the same and, yes, the grumpiness was there even then.
Yes, a great film! The drummer was Larry Richie and the bassist Michael Mattos. When the stage version came to London (British audiences weren't ready for it and it soon folded) some of the actors shared lodgings with a jazz-loving student friend of mine. As a treat they took him to a rehearsal to meet Jackie.
