I saw Frank Zappa five times back in the day. He put on an awesome show.
I think I saw Zep opening for the Paul Butterfield Blues Band at the Old Boston Tea Party when it was in the South End.
(((I say “I think” because if you can actually REMEMBER the 60’s, you probably weren’t there! LOL)))
I never got into his music back then. He was just a little too weird for up-tight me. LOL!
You must have had a REALLY good time at those concerts. :)
