Best 1982 Police Picnic, CNE Toronto, The Police, Talking Heads, English Beat, Joan Jett, among others. I was 16 and had crap seats. Went with my brothers friends and they said 'stick close to us and do what we do'. We got up to the rail, jumped on the field and ran like hell for the crowd. Security didn't look much for us and we spent the show about 50ft from the stage. Great memories.
Worst - Cabaret Voltaire, Concert Hall, Toronto 1985ish. Basically had tape machines on stage playing their music and the crowd stood around trying to look cool. wtf was the point of that was what I asked myself on the way out.
