Ian Gillan and disliked live albums in general. He tended to go into the studio after the rest of the band had recorded and finished the backing tracks, particularly for "Who Do We Think We Are", to lay down his vocals separately. He had been continually at loggerheads with Blackmore, disagreeing about music regularly, which culminated in Gillan writing "Smooth Dancer" about him. While on tour in Dayton, Ohio, he sat down and wrote a resignation letter to the band's managers, stating he intended to leave the band, effective from 30 June 1973. After his departure from Deep Purple, Gillan retired from
Neo (British band) part of Ultravox. North sacked Paul Simon, and included session players in his project: ex-ZZebra members, Steve Byrd on guitar and John McCoy on bass, and Bryson Graham on drums. They recorded an album in Ian Gillan's studio, and after Gillan heard them, he hired Byrd and McCoy away from North. Gillan and the ex-Neo musicians formed Gillan. Only Graham stayed with North. North renewed Neo again with Steve Wilkin (ex-Wired and Masterwitch) on guitar, Nick South on bass and Graham on drums, but shortly afterwards South and Graham were replaced by Mik Sweeney and Derek Quinton, respectively.
