Some great reminisences there Bob, thanks for that. I was living in downtown Montreal at the time (late 60's early 70's) and saw many of the acts you mentioned at the Back Door. I recall a John Hammond gig where the audience, at encore time, was requesting tunes that weren't exactly firing John up so I called for "Hootchie Cootchie Man" and John says "That's my man" and launches into his great version of that tune. My slight brush with fame.
