I have, when he played drums in the Turtles. He was fantastic. I told him, "You know, you're wasting your skills with Flo and Eddie [Howard and Mark stole those nicknames from me years later]. You should leave 'em, and come play drums in my new band, Crosby, Stills and Fergusen." He took my advice, but had to wait because his band was still touring. By the time he joined, I'd left CS&F to play catcher for the Dodgers, where I made a still legendary throw in the World Series playing right field. Not many people know this.
