“Revolution” is a song by the English rock band the Beatles, written by John Lennon and credited to the Lennon–McCartney partnership.

Three versions of the song were recorded and released in 1968, all during sessions for the Beatles’ self-titled double album, also known as “the White Album”.

A slow, bluesy arrangement (titled “Revolution 1”) that would make the final cut for the LP; an abstract sound collage (titled “Revolution 9”) that originated as the latter part of “Revolution 1” and appears on the same album; and the faster, hard rock version similar to “Revolution 1”, released as the B-side of “Hey Jude”. Although the single version was issued first, it was recorded several weeks after “Revolution 1”, as a remake specifically intended for release as a single.
