So sad. My 1st concert was Van Halen leading off for Ozzy on their 1st tour at the Spectrum in Philly. It was general admission and I remember fans chanting "1, 2, 3, 4 OPEN UP THE Fucking DOOR!". The mob pushed so hard a window broke and cops rushed in on horses. Being from the suburbs and just 18, I was scared to death. Great concert though.
