The following list details musicians who have been and still are members of the English progressive rock band Yes since its formation in 1968. Their latest lineup includes bassist Billy Sherwood, guitarist Steve Howe, drummer Alan White, keyboardist Geoff Downes and lead vocalist Jon Davison. The band was split between 1981 and 1982 and on hiatus from 2004 to 2008. Squire was the only member to be part of every one of the band's incarnations until Yes announced on 19 May 2015 that he was suffering of acute erythroid leukemia and was replaced (at the most) on his live duties by returning member Billy Sherwood. Squire died from leukemia on 27 June 2015.
