Half the time Led Zep were sitting in chairs playing...man were those guys shot out back then....it was the weekend when Robert Plant's son died too but Bill Graham wouldn't tell him untill after the show...we had to wait 2 hours after Rick Derringer finished before Led Zep came out and then finally Robert Plant walks out drinking a hinekin...we were getting crushed in front of the stage so we left...WTF...still remember it like it was yesterday thow...
