"Revolution" is a song by the English psychedelic rock band Tomorrow.
The song also appeared on the group's self-titled album Tomorrow in February 1968.
The 1999 CD reissue of Tomorrow also includes a previously unreleased studio demo recording of the song.
Tomorrow performed this song for John Peel's radio show on the BBC, and there is also a live recording on the album 50 Minute Technicolor Dream.
AllMusic writer Richie Unterberger called "Revolution" an "infectious hippie anthem".
