Among the topics Jerry discussed included the original Acid Tests, Neal Cassady's driving, tanks on Haight Street, indecision about what songs to play, cosmic psychedelic experiences, the arrangement of I Know You Rider, how rap is not music ("it's talking"), dividing technique from substance, and modeling his playing based on personal exploration with psychedelics (e.g. "playing for his life" when he accidentally ate a cake laced with "800 hits" of LSD).
The best quote about Jerry's paranoia after he got dosed backstage with cake and started tripping balls: "This place is full of mafia guys and they are trying to kill me! They're gonna fucking kill me!"
Oh, and Happy Birthday, Jerry!
