Ian Gillan band, who had not had any holiday since their initial rehearsals at Hanwell. He started drinking, and relationships between him and the rest of the band became strained, particularly with Blackmore. On 6 November 1971, he collapsed with hepatitis while waiting to board a plane in Chicago, cancelling the remainder of a US tour. By December 1972, having recorded "Machine Head", "Made in Japan" and the yet to be released "Who Do We Think We Are" with Deep Purple, Gillan finally decided the workload had driven him to exhaustion. Unlike some band members, he was unhappy about "Made in Japan",
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.
