"Fun Factory" was a single released by The Damned in 1990.
The band had split in 1989, but would shortly be reforming again for touring. Captain Sensible was set to return, and sought the other band members' permission to reissue the track "Fun Factory", recorded in late 1982 (and featuring King Crimson's Robert Fripp on guitar), but shelved when the Damned's record company (Bronze Records) went bankrupt in early 1983. While it is not attached to any Damned album, it has been issued on several compilations.
The B-side was a solo track by Sensible, remixing a track from his 1989 solo album Revolution Now. The bonus tracks on the 12" and CD singles were also solo Sensible works.
