There were a bunch of awesome heavy metal bands that day.
Quiet Riot, Mötley Crüe, Ozzy Osbourne, Judas Priest, Triumph. Scorpions and Van Halen
Van Halen had an interesting intro as well. The local radio station decided to go backstage into their dressing room just prior to their set. With a video camera. What followed was footage of several band members banging away with groupies. What followed on stage was ok...David Lee Roth, however, was pretty drunk and doing a TERRIBLE job singing.
