I saw Tull, musta been in the eighties, don't think it was seventy nine.During imtermission some bum looking guy, which was part of the show came on stage and threw up in a large lookin trash can, then the band came out, one by one, and they would pull a musical instrument out of the trash can. It was a badass and a very fun show. We sit close to the stage and they had this beachball, that would vibrate with the music as it floated thru the air or it seemed to, might a been the buzz I had. Dont remember no opening show. They closed the show I think with the lights out, and when the lights came back on, the band was gone. The song The Last Walz by the band started playing, that even sounded good.
