I didn't attend this concert, but talked with a person named Kathleen who went to Indio High School and was at the school's prom where Fishbone played. Besides relaying some information about the prom, she also sent me a couple of photos from the prom book! A big thank you goes to her for providing this information and photos!

Apparently, the band The Untouchables were originally supposed to play this prom. They had to cancel, and Fishbone ended up playing!
