I saw them twice in Tuscaloosa. I believe Ian Anderson said at the beginning of the second time, it was the first performance of Thick as a Brick. Best 2 concerts I ever saw!
Aqualung- 1972 in El Paso.
It was great!
I saw Tull in Jenison Field House at Michigan State University in about 1972-73. They were promoting their just released album, Passion Play. Seats were general admission, i.e. not reserved. We were waiting in line for quite a while when the doors finally opened. Then I experienced something terrifying. I was being pushed by a massive crowd of people and I had no control over it. I made it through tfine, but I learned that was an experience I should be able to avoid for the rest of my life.
Despite lost acoustics the concert was great. They played Locomotive Breath, Living in the Past, both sides of Thick as a Brick and all of Passion Play. Ian Anderson was awesome.
