My first at age 13 was Alice Cooper, Welcome to my Nightmare tour, still top 3 concert for me, again at Penns Peak few yrs ago.
My 2nd concert , Pink Floyd, Dark Side Moon tour and again Animals tour.
Some guy sold my buddy 2 tickets for Pink Floyd in '75. We were at the trolly stop on Erie Ave when this guy decided he wanted to buy back the tickets. My buddy & I ran away from him, jumped on a trolley a few stops away and off to the Spectrum. We ended up sitting with his pals!
2x Alice Cooper
2x Pink Floyd
Almost every concert I saw was at the Spectrum in Phila. Saw a bunch more but can't quite remember.
Had tickets for Led Zepplin but than they cancelled when Plant's son suddenly died.
