<P> The song "San Francisco (Be Sure to Wear Flowers in Your Hair)" was written by Phillips and sung by McKenzie, released in May 1967, to promote the event . </P> <P> With two huge singles behind them, Jefferson Airplane was one of the major attractions of the festival, having built up a large following on the West Coast . </P> <P> Although already a big act in the UK, and now gaining some attention in the US after playing some New York dates two months earlier, The Who were propelled into the American mainstream at Monterey . The band used rented Vox amps for their set, which were not as powerful as their regular Sound City amps which they had left in England to save shipping costs . At the end of their frenetic performance of "My Generation", the audience was stunned as guitarist Pete Townshend smashed his guitar, smoke bombs exploded behind the amps and frightened concert staff rushed onstage to retrieve expensive microphones . At the end of the mayhem, drummer Keith Moon kicked over his drum kit as the band exited the stage . During Jimi Hendrix' stay in England he and the Who had seen each other perform, they were both impressed with and intimidated by each other, so neither wanted to be upstaged by the other . They decided to toss a coin, with The Who ending up performing just before Hendrix . </P> <P> "The Grateful Dead were beautiful . They did at top volume what Shankar had done softly . They played pure music, some of the best music of the concert . I have never heard anything in music that could be said to be qualitatively better than the performance of The Dead, Sunday night ."--Michael Lydon, author of Flashbacks (2003) </P>
