Bon Jovi's first tour, opening for the Scorpions Love at first sting - Allentown Fairgrounds.
A lot was being thrown at the stage during the Bon Jovi set, apparently most of the people wanted to hear the Scorpions - Great show.
Saw Iron maiden there a few months later.
Between there and the Philly Spectrum I saw, Rush, Yes, Nugent open for Aerosmith, Metallica, Judas Priest and a bunch of others I can't recall now, and some I probably couldn't quite tell you at the time because of something like a liter bottle of Canadian Windsor and some dried greenish brown plant like substance. All I remember is there weren't enough soft pretzels or Pepsi on the planet at that point in time.
When I lived in SoCal I saw a bunch of good shows, Motorhead, Metallica and GNR show was great but holy hell Slash's rig was killing me and we left early. IIRC a few months earlier Jeff Beck played through Slashes rig for a show and he ended up with severe tinnitus on Locomotive.
My body and head were numb for nearly 2 days after that show at the LA Coliseum and we were about 60 yards back from the stage. Black Album where James was still nursing the burns from the earlier show with the riot due to the pyro accident no alcohol to avoid another potential riot. Warrant, I think Firehouse opened for them.
