Steve Marriott and Ronnie Lane already had the melody for the song. However they had no lyrics so their manager Don Arden brought in "Move It
" songwriter Ian Samwell to provide the words. Kenney Jones recalled to Uncut

' – and this really suited the power of Steve's voice. The style was very indicative of the time and we loved it."
