List of UFO members

[9] Due to increased problems stemming from his alcohol abuse, Schenker quit UFO after a show on 29 October 1978, with Chapman returning to take his place shortly after.

[10] Raymond left two years later and was briefly replaced by John Sloman, before Neil Carter took his place midway through the recording of The Wild, the Willing and the Innocent.

[21] A new lineup of the band including guitarist Rik Sanford and drummer Fabio Del Rio began working on a new album later in the year,[22] and after brief stints with Tony Glidewell and Erik Gamans on guitar, UFO broke up for a second time in 1989.

[23][24] UFO returned for a third time in 1991, with Mogg and Way joined by guitarist Laurence Archer, drummer Clive Edwards and, later, keyboardist Jem Davis.

[28] The guitarist quit suddenly after a show on April 24, 1998, with Wright and Raymond following soon after; due to an agreement signed by the band members, Mogg and Way were unable to use the name UFO without Schenker, and briefly considered renaming the group Lights Out.

[31] Dunbar returned in 2002 to perform on Sharks,[32] which was the band's last album to feature Schenker who quit in January 2003, relinquishing his part-ownership of the name in order that UFO could continue.

[34] Bonham remained in UFO until 2005, when Parker returned to the group,[35] and in 2008 Rob De Luca joined in place of Way, after filling in for him on an initially temporary basis.

[38] In September 2022, it was announced that Phil Mogg had suffered a heart attack and remaining dates of the farewell tour were cancelled, save for occasional shows afterwards.
