Rainbow (rock band) steered Deep Purple through a significant personnel change, with Ian Gillan and Roger Glover being replaced by David Coverdale and Glenn Hughes. However, the new members were keen to add new musical styles and Blackmore found his request to record the Steve Hammond-penned "Black Sheep of the Family" with "Sixteenth Century Greensleeves" turned down by the band. He decided to record the song with Dio instead, using Dio's band Elf as additional musicians. He enjoyed the results, and a full album, billed as "Ritchie Blackmore's Rainbow" was recorded between February and March 1975 at Musicland Studios in Munich, Germany. The
Ian Gillan song "Mitzi Dupree" on "The House of Blue Light" is the original demo as Blackmore refused to re-record it. This culminated in Blackmore calling a rehearsal session without Gillan. After an acrimonious argument, Glover told Gillan, "Ian, you've gone too far this time," and he was fired. Gillan, meanwhile, formed a new version of Garth Rockett and the Moonshiners with keyboardist Mark Buckle, bassist Keith Mulholland, drummer Louis Rosenthal and guitarists Harry Shaw and Steve Morris.
