The Beatles: John Lennon (vocals, guitar, keyboards); Paul McCartney (vocals, guitar, bass); George Harrison (vocals, guitar); Ringo Starr (vocals, drums).

Starting out as a sing-a-long vehicle for Ringo Starr on REVOLVER, "Yellow Submarine" became the inspiration for the 1968 animated feature film of the same name. Most of the soundtrack was composed and orchestrated by George Martin, but the remaining six songs were far from being Beatle cast-offs. George Harrison's two contributions, "Only A Northern Song" and "It's All Too Much" mark the adventurously experimental phase the Beatles were in at that time and dabble in woozy psychedelic shadings laced with orchestrations that continued to influence cutting-edge pop artists for decades to come. Along with the aforementioned "Yellow Submarine," other Lennon/McCartney compositions include the good-time, skiffle-flavored "All Together Now," the Lennon-driven rocker "Hey Bulldog," and "All You Need Is Love"--the unofficial flower-power anthem.
