The Beatles - I Want You

"I Want You (She's So Heavy)" is a song by The Beatles, from their album Abbey Road. It was written by John Lennon, although it is credited as a Lennon/McCartney collaboration.
The song is an unusual Beatles' composition for a variety of reasons, namely its length (nearly eight minutes), small number of lyrics (only fourteen different words are sung), three-minute descent through the same repeated guitar chords (a similar arpeggiated figure appears in another Lennon contribution to the album, "Because", as well as McCartney's "Oh! Darling"), and abrupt ending. It is also one of the last songs that The Beatles mixed as a group, on 20 August 1969.
The song was rehearsed several times during the Get Back/Let It Be sessions; the basic track and John's guide vocal (which is used in the master) were recorded at Trident Studios on 22 February 1969, shortly after filming for the film project ended. John and George overdubbed multi-tracked heavy guitar overdubs on 18 April 1969, and Billy Preston overdubbed keyboards, and conga drums were also added on 20 April 1969. "I Want You" then received the "She's So Heavy" vocals on 11 August 1969 and thus the title was changed to "I Want You (She's So Heavy)".
