 Keith John Moon was born to Alfred Charles ( Alf ) and Kathleen Winifred ( Kit ) Moon on 23 August 1946 at Central Middlesex Hospital in northwest London , and grew up in Wembley . He was hyperactive as a boy , with a restless imagination and a particular fondness for The Goon Show and music . Moon attended Alperton Secondary Modern School after failing his eleven plus exam , which precluded his attending a grammar school . His art teacher said in a report : " Retarded artistically . Idiotic in other respects " . His music teacher wrote that Moon " has great ability , but must guard against a tendency to show off . "
