I saw Tull several times in the early 70s. They were always really exceptional.
I also got to see Roland Kirk about 5 nights in a row at the Esquire Showbar in Montreal. I was friends with the piano player, so I had a seat at the band table beside the stage, and got in free. I'm glad I wasn't sitting in front because he sprayed spit all over. The man was a force of nature, sometimes playing 3 horns at once. He was a master of rotary breathing and could exhaust an audience with a 20 minute non-stop solo. good times all around. R.
