It was made clear that Rodgers would not be replacing Queen's former lead singer, Freddie Mercury, who died on 24 November 1991. He would simply be "featured with" former Queen members. Former Queen bass guitarist John Deacon declined to participate in the collaboration due to his retirement in 1997. The group's three principal members May, Taylor and Rodgers were supplemented on tour by Queen's former touring keyboard player Spike Edney, rhythm guitarist Jamie Moses, and bass guitarist Danny Miranda who had previously worked with Blue Öyster Cult. Throughout their career the band completed two world tours, issued the first studio album for Queen in nearly 15 years entitled "The Cosmos Rocks", and released two live albums and three live DVDs.
