Dude, I think I was there. It was 1979, "Ambrosia" was the opening act. I got crushed at the gate at many of those general admission concerts, particularly at an Emerson Lake & Palmer concert. Man, those were the days. If you got bored by the music you could go outside and cruise for chicks. I spent many a night at the Sportatorium seeing bands that I didn't even like (Foreigner, Heart, Rush, etc) just because there was nothing else better to do. Pre-South Beach Miami was pretty boring.
Dang, I miss Ambrosia!!
