 In May 1966 , Moon discovered that the Beach Boys ' Bruce Johnston was visiting London . After the pair socialised for a few days , Moon and Entwistle brought Johnston to the set of Ready Steady Go ! , which made them late for a show with the Who that evening . During the finale of " My Generation , " an altercation broke out on stage between Moon and Townshend which was reported on the front page of the New Musical Express the following week . Moon and Entwistle left the Who for a week ( with Moon hoping to join the Animals or the Nashville Teens ) , but they changed their minds and returned .
