This was one of three benefits for victims of the 1989 Loma Prieta Earthquake the Bill Graham put on that date -- one in Watsonville, this show and the third at The Cow Palace. Only Bill would have attempted something like this -- and then pull it off perfectly!
"Electric Music For The Mind And Body": the first acid rock album ever released (before "Surrealistic Pillow"). Well... O.K..--- "Takes Off", but the general public didn't really know.
I saw this amazing band at some kind of pizza parlor in Seattle, with actual hookers hanging around the front door. The acid made it weird. They were/are extraordinary. Pay John was led in basically doubled over at the waist. Took the stage, picked up his fiddle, and straightened all the way up. Tore the roof.
