I saw The Who (in '68?) on their Magic Bus tour. I still can't hear out of my right ear. Believe it or not, this concert was in a suburb of Chicago (The Jaguar in St. Charles), in a place about the half the size of a basketball court, ten foot ceiling, no chairs, and a cement floor. We stood right next to the stage (and the speakers, unfortunately). They did the show and tore up all the equipment, and most of what was near the stage, including the ceiling.
I saw them several times after that. I think the best concert I ever saw was The Who backed up by Lynard Skynard, must have been around '73. I believe it was touted as "The Tommy Tour". They ended the show with "See Me, Feel Me" along with an awesome light show that lit up the entire auditorium. They left the stage after that song, they didn't come back for an encore during that tour. The entire stadium stood on their chairs waving their hands and screaming for almost a half hour after they left the stage.
The Kids Are Alright!!!
