The recording of this album had its peculiarities. While some songs were created with the film in mind, others were material the band already had and had not been released. For example, George Harrison's "Only a Northern Song" was originally intended for Sgt. Pepper's Lonely Hearts Club Band and much of it was recorded since 1967. "It's All Too Much," also by Harrison, was recorded shortly before Sgt. Pepper's and had to be shortened for this release. On the other hand, "Hey Bulldog" and "All Together Now" seem to have been conceived for the film, although there are records that "Hey Bulldog" was recorded during the filming of the "Lady Madonna" clip. The B-side of the record is entirely dedicated to George Martin's compositions, which bring the film's soundscapes to life.
Despite some pieces already being known, the album had its moment. It reached the top positions on the charts, both in the United Kingdom and the United States. The critical reception was varied; some felt that the band's material sounded a bit dated compared to their previous works, but George Martin's orchestral work received praise. Originally, the possibility of Yellow Submarine being a shorter EP, without the orchestral music and including "Across the Universe," was considered, but ultimately the version we know was chosen, which has been reissued on compact disc several times over the years.
