Finish the lyric from The Beatles' 'Yellow Submarine': 'We all live in a...'

The lyric “We all live in a...” is completed by “yellow submarine” in The Beatles’ song “Yellow Submarine.”

Released in 1966, the song was written primarily by Paul McCartney, with songwriting credit shared with John Lennon. Ringo Starr sings the lead vocal, giving the track its playful, storybook character. It appeared on the album Revolver and was also released as a single paired with “Eleanor Rigby.”

The submarine is usually understood as a colorful fantasy setting rather than a literal vessel. The recording uses unusual sound effects, including bubbles, bells, chains, and nautical noises, to reinforce its imaginative atmosphere.

A common mix-up is confusing the song with the 1968 animated film Yellow Submarine. The film takes its title from the song, but the lyric itself comes from the 1966 recording.
