<P> In 1966 the Who released "I'm a Boy", about a boy dressed as a girl, taken from an abortive collection of songs called Quads; "Happy Jack"; and an EP, Ready Steady Who, that tied in with their regular appearances on Ready Steady Go! The group continued to have conflict; on 20 May, Moon and Entwistle were late to a gig having been on the Ready Steady Go! set with The Beach Boys' Bruce Johnston . During "My Generation", Townshend attacked Moon with his guitar; Moon suffered a black eye and bruises, and he and Entwistle left the band, but changed their minds and rejoined a week later . Moon kept looking for other work, and Jeff Beck had him play drums on his song "Beck's Bolero" (with Page, John Paul Jones and Nicky Hopkins) because he was "trying to get Keith out of the Who". </P> <P> To alleviate financial pressure on the band, Lambert arranged a song - writing deal which required each member to write two songs for the next album . Entwistle contributed "Boris the Spider" and "Whiskey Man" and found a niche role as second songwriter . The band found they needed to fill an extra ten minutes, and Lambert encouraged Townshend to write a longer piece, "A Quick One, While He's Away". The suite of song fragments is about a girl who has an affair while her lover is away, but is ultimately forgiven . The album was titled A Quick One (Happy Jack in the US), and reached No. 4 in the UK charts . It was followed in 1967 by the UK Top 5 single "Pictures of Lily". </P> <P> By 1966, Ready Steady Go! had ended, the mod movement was becoming unfashionable, and the Who found themselves in competition on the London circuit with groups including Cream and the Jimi Hendrix Experience . Lambert and Stamp realised that commercial success in the US was paramount to the group's future, and arranged a deal with promoter Frank Barsalona for a short package tour in New York . The group's performances, which still involved smashing guitars and kicking over drums, were well received, and led to their first major US appearance at the Monterey Pop Festival . The group, especially Moon, were not fond of the hippie movement, and thought their violent stage act would stand in sharp contrast to the peaceful atmosphere of the festival . Hendrix was also on the bill, and was also going to smash his guitar on stage . Townshend verbally abused Hendrix and accused him of stealing his act, and the pair argued about who should go on stage first, with the Who winning the argument . The Who brought hired equipment to the festival; Hendrix shipped over his regular touring gear from Britain, including a full Marshall stack . According to biographer Tony Fletcher, Hendrix sounded "so much better than the Who it was embarrassing". The Who's appearance at Monterey gave them recognition in the US, and "Happy Jack" reached the top 30 . </P> <P> The group followed Monterey with a US tour supporting Herman's Hermits . The Hermits were a straightforward pop band and enjoyed drugs and practical jokes . They bonded with Moon, who was excited to learn that cherry bombs were legal to purchase in Alabama . Moon acquired a reputation of destroying hotel rooms while on tour, with a particular interest in blowing up toilets . Entwistle said the first cherry bomb they tried "blew a hole in the suitcase and the chair". Moon recalled his first attempt to flush one down the toilet: "(A) ll that porcelain flying through the air was quite unforgettable . I never realised dynamite was so powerful ." After a gig in Flint, Michigan on Moon's 21st birthday on 23 August 1967, the entourage caused $24,000 of damage at the hotel, and Moon knocked out one of his front teeth . Daltrey later said that the tour brought the band closer, and as the support act, they could turn up and perform a short show without any major responsibilities . </P>
