Who Do We Think We Are is the seventh studio album by the English hard rock band Deep Purple, released in 1973. It was Deep Purple's last album with singer Ian Gillan and bassist Roger Glover until 1984’s Perfect Strangers. Musically, the record showed a move to a more blues-based sound, even featuring scat singing. Although its production and the band's behaviour after its release showed the group in turmoil, with frontman Gillan remarking that "we'd all had major illnesses" and felt considerable fatigue, the album was a commercial success. Deep Purple became the top-selling U.S. artist in 1973. The album featured the energetic hard-rock single "Woman from Tokyo," a live staple of the band's since the album's release. Recording Who Do We Think We Are was recorded in Rome in July 1972 and Walldorf near Frankfurt in October 1972, using the Rolling Stones Mobile Studio. "Woman from Tokyo," the first track recorded in July, is about touring Japan for the first time (e.g. the lyric "Fly into the Rising Sun"). The only other track released from the Rome sessions is the outtake "Painted Horse." The rest were recorded in Frankfurt after more touring (including Japan, which yielded Made in Japan). The group, riven with internal strife, struggled to come up with tracks they agreed upon. Members were not speaking to each other and many songs were finished only after schedules were arranged so they could record parts separately. Of "Mary Long," Gillan said: "Mary Whitehouse and Lord Longford were particularly high-profile figures at the time, with very waggy-waggy finger attitudes… It was about the standards of the older generation, the whole moral framework, intellectual vandalism – all of the things that exist throughout the generations… Mary Whitehouse and Lord Longford became one person, fusing together to represent the hypocrisy that I saw at the time." Ian Gillan left the band following this album, citing internal tensions – widely thought to include a feud with guitarist Ritchie Blackmore. However, in an interview supporting the Mark II Purple comeback album Perfect Strangers, Gillan stated that fatigue and management had a lot to do with it: Added Jerry Bloom, editor of the book More Black than Purple: The last Mark II concert in the 1970s before Gillan and Glover left was in Osaka, Japan on 29 June 1973.
