I saw Frank Zappa and the Mothers of Invention when Flo and Eddie from the Turtles were part of the group. State University of NY at Stony Brook about 1972, I was a student there. That was an incredible concert. "Billy the Mountain" was the hit. On the album, it is one full side, around 20 minutes. Live in concert it had to go on for around an hour. I never saw more weirdos in one place before or ever since. Sorry I can't remember more about it, but that's the way things went back then.
