I saw the band live on March 21st, 1974 in the gym at Quincy College, Quincy, Illinois. I was 15. Great show, not many songs but each one was damn near 15-30 minutes long. I treasure a bootleg I made from it. This was also where I got my first few good whiffs of pot!
Now, my question, and it's going to make me look silly...Are the two drummers, Pete R. and Pete H., the same guy? They certainly LOOK similar. The drummer I saw was Pete R. and this show would have been during or near the "Ma" tour.
