The band found a new singer called Ian Gillan and a new bass player called Roger Glover, forming Mark II. Jon Lord used to play in orchestras, and at this time, wanted to go back to them and base the Deep Purple sound around that. Whilst the band did perform as an orchestra (with new singer Ian Gillan writing lyrics) gaining the band some publicity, Gillan and Blackmore were not happy about the band being associated with orchestras, and were firm about Deep Purple being a hard rock band, though Jon Lord would write another orchestral piece for the band.
