披头四於1966年发表的＜Yellow Submarine＞，原收录於1966的《Revolver》专辑中，当时曾在美国排行榜上获得亚军，轻松谐趣的曲调，深受儿童的喜欢，也成为当时一些儿童合唱团的演唱曲。1968年英国电视界决定制作一部以披头四为主角的卡通影片，於是以＜黄色潜水艇＞作为题材，获得相当高的评价，成为动画经典。片中亦采用包括＜Nowhere Man＞、＜All You Need Is Love＞等多首披头四的经典作品。1969年所发行原声带也收录几首乔治马丁所谱写的古典配乐。披头四首度尝试『童话式影片』创作，是披头四另一张半概念性专辑

The only Beatles album that could really be classified as inessential, mostly because it wasn't really a proper album at all, but a soundtrack that only utilized four new Beatles songs. (The rest of the album was filled out with "Yellow Submarine," "All You Need Is Love," and a George Martin score that held little appeal to rock listeners.) What's more, the four new tracks were little more than pleasant throwaways that had been recorded during 1967 and early 1968. These aren't all that bad; "All Together Now" is a kiddieish singalong, "Hey Bulldog" has some mild Lennon nastiness, and Harrison's "It's All Too Much" is highlighted by some tidal waves of feedback guitar. It would have been far better value if it had been released as a four-song EP (an idea the Beatles even considered at one point, with the addition of a bonus track in "Across the Universe," but ultimately discarded).
