Peter "Dougal" Butler is a British author and retired roadie. He is best known for being Keith Moon's personal assistant during the 1970s, and for publishing several books about Moon's life, Full Moon and Keith Moon ? A Personal Portrait. Butler grew up in London at the same time as The Who became successful. He left school at 15 and worked for HM Customs and Excise before becoming a roadie for the band in 1967 or 1968. According to Butler, one of his early tasks for the band was to provide a getaway car so that Pete Townshend could steal a guitar from Jim Marshall's music shop in Ealing. He quickly became friends with Moon, regularly visiting the Speakeasy Club and after a spell of becoming personal assistant to Entwistle for 18 months, decided to switch to looking after Moon. Butler later described being Moon's personal assistant as demanding work, recalling "what you learnt was what was going on in his mind and tried to be a step or two ahead but he was very unpredictable." He followed Moon to Los Angeles where they lived in the mid-1970s, but found Moon's ability to attract the wrong crowd being increasingly problematic.
