He writes:This seems to have just sur­faced: the most com­plete record­ing of the Human Be-In in Gold­en Gate Park in 1967 that I have ever seen, by far. It opens with Allen Gins­berg and Gary Sny­der chant­i­ng, Michael McClure fol­lows, and the Grate­ful Dead (with adorable footage of Allen danc­ing) pop up at about 14:00. The Human Be-In pre­cip­i­tat­ed the leg­endary Sum­mer of Love, and made San Francisco’s Haight-Ash­bury the epi­cen­ter of the bur­geon­ing hip­pie move­ment. The Be-In fea­tured all the lumi­nar­ies of psy­che­del­ic counter-cul­ture, includ­ing Tim­o­thy Leary, Allen Gins­berg, Gary Sny­der, Richard Alpert (Ram Dass), Dick Gre­go­ry, Lenore Kan­del, and Jer­ry Ruben. Many of the Haight’s best musi­cal acts also per­formed, includ­ing the Grate­ful Dead and Quick­sil­ver Mes­sen­ger Ser­vice.”
