soundtrack LP Yellow Submarine Magical Mystery Tour Revolver All You Need Is Love title track
The group were less involved with Yellow Submarine, which featured the band appearing as themselves for only a short live-action segment. Premiering in July 1968, the film featured cartoon versions of the band members and a soundtrack with eleven of their songs, including four unreleased studio recordings that made their debut in the film. Critics praised the film for its music, humour and innovative visual style. A soundtrack LP was issued seven months later; it contained those four new songs, the title track (already issued on Revolver), "All You Need Is Love" (already issued as a single and on the US Magical Mystery Tour LP) and seven instrumental pieces composed by Martin.
