The Human Be-In was announced on the cover of the first issue of the "San Francisco Oracle" as "A Gathering of the Tribes for a Human Be-In". Speakers at the rally included Timothy Leary, Richard Alpert (soon to be more widely known as 'Ram Dass'), and poets like Allen Ginsberg, who chanted mantras, and Gary Snyder. Leary set the tone that afternoon with his famous phrase "Turn On, Tune In, Drop Out". Other counterculture leaders who were there included comedian Dick Gregory, Lenore Kandel, and Jerry Rubin. The Hells Angels, at the peak of their 'outlaw' reputation, looked after lost children. Local rock bands such as Grateful Dead and Quicksilver Messenger Service provided the music, and Owsley "Bear" Stanley provided massive amounts of his "White Lightning" LSD to the gathered masses.
