Wings, also known as Paul McCartney and Wings, were an Anglo-American rock band formed in 1971 by former Beatle Paul McCartney with his wife Linda, session drummer Denny Seiwell, and former Moody Blues guitarist Denny Laine. Wings were noted for frequent personnel changes as well as commercial success, going through three lead guitarists and four drummers. However, the core trio of the McCartneys and Laine remained intact throughout the group's existence.

The song starts with the sound of a vibraphone, chiming the first eight notes from the Westminster Quarters, before the rhythm begins. The lyric name-checks several famous people as well as McCartney's paternal aunt Gin and his brother Michael. Phil and Don Everly (known as the Everly Brothers) are named along with Martin Luther. Uncle Ernie is named; this was the character Ringo Starr sang in the London Symphony Orchestra's recording of the Who's Tommy. "Let 'Em In" is noted for the false fade out, which, however, becomes loud for the last two notes of the song as it ends. The song makes use of the piano, drums, brass, including a trombone solo, and wind instruments, featuring flutes, plus backup vocals from Linda and other members of Wings.
