The B-side of "Hey Jude" was "Revolution", a song by Lennon in reaction to the Soviet Union's action against student protests in Czechoslovakia, the ongoing war in Vietnam, and calls around the world for a revolution against the status quo. He hoped the band's first recording of the song would become their next single, but it was rejected as too slow and too long. He re-recorded the song, faster this time, lying on the studio floor to give the vocals more "punch". "Hey Jude" was seen as a bigger potential hit though, so "Revolution" became the B-side. The Beatles performed both songs live for an audience, and the performances appeared on "The David Frost Show" in England, and "The Smothers Brothers Comedy Hour" in America.
