I had a friend, who has since passed away, that was a Tull fanatic. Between 1975 and 1979, we saw him 2 or 3 times around Los Angeles. Always different venues like The Forum, Long Beach Arena, Dorothy Chandler, and maybe even the Coliseum.
We always had a great time, the shows were always fantastic, and we were always higher than a kite. Hence, my memory is kaput....
