Overview
"Don't Let Me Down" is a song by the English rock band the Beatles, recorded in 1969 during the Let It Be sessions. It was written by John Lennon and credited to the Lennon–McCartney songwriting partnership. The band recorded the song with keyboardist Billy Preston; the single release with "Get Back" was credited to "the Beatles with Billy Preston". Originally released as a B-side, producer Phil Spector excluded the song from Let It Be. However, it was eventually included on an alternative mix of the album, Let It Be... Naked.
Composition
Written by John Lennon as an anguished love song to Yoko Ono, it was interpreted by Paul McCartney as a "genuine plea", with Lennon saying to Ono, "I'm really stepping out of line on this one. I'm really just letting my vulnerability be seen, so you must not let me down."
The song is in the key of E major and is in time during the verse, chorus and bridge, but changes to in the pick-up to the verse. It grew (like "Sun King") from the Fm7–E changes from Fleetwood Mac's "Albatross" with McCartney arranging instrumental and vocal parts and George Harrison adding a descending two-part lead guitar accompaniment to the verse and a countermelody in the bridge. Alan W. Pollack states that "the counterpoint melody played in octaves during the Alternate Verse by the bass and lead guitars is one of the more novel, unusual instrumental touches you'll find anywhere in the Beatles catalogue."
