Elton John in Seattle, 1980.
Kinda funny story to go with that. I went with my best friend, and he was a bit of a poser in those days. We were 19, but he had been drinking Seagram's 7 & diet 7-up beforehand (I abstained), then started smoking a Swisher-Sweet. (You could still smoke in auditoriums back then.)
About halfway thru the concert he starts to turn green, and unfortunately for the huge guy sitting in front of us who was wearing a hoodie, he proceeded to fill the hoodie with, well, you know. The guy screams and jumps up, spinning around with his fists clenched, which flung some of the ejecta onto his girlfriend. She screams, and when the boyfriend turned back to his girl, I grabbed my buddy by the shirt collar and beat feet out of there, so we only saw half of the concert. He still claims I saved his life that night. I dunno, maybe. But I still feel bad for that guy and his girlfriend.
