I distinctly remember Fee Waybill and the Tubes as the supporting act and when he came out on stage in those ridiculous platform shoes I almost wet myself laughing. I especially remember Bill Graham's people dumping Frisbees onto the stage and flinging them into the audience because Zeppelin was late. I remember because I almost had my head taken off by one as I crouched over to get something out of my backpack and I felt something whiz through my hair and nail the guy behind me in the throat. Great concert but I don't think the guy behind felt that way.
