Small world. I was at the Coliseum that same week, only I was there for the USC Trojans (they got upset by Arizona) despite Marcus Allen running 200+ yards for the fifth straight game. The Stones played the night before and would play again the night after. During the football game, you could see the staging on one end of the field.
I do remember the reviews of the show and how Prince got practically booed off the stage. On the other hand, George Thorogood brought down the house.
