The song was All Together Now, which was written by Paul McCartney specifically for the Yellow Submarine film. It was a straightforward recording, made even without the presence of producer George Martin.
McCartney overdubbed a bass guitar part, followed by his lead vocals, for which he was joined by Lennon and Harrison in the chorus. The final track on the tape was filled with Lennon's lead vocals in the bridge, more bass drum and finger cymbals, and the final singalong.
Six mono mixes were then made, and the song was complete and ready for inclusion in the film, and for release on the accompanying soundtrack LP.
