"Don't Let Me Down" is a song by The Beatles, recorded in 1969 during the Get Back (Let It Be) sessions. Richie Unterberger of Allmusic called it "one of the Beatles' most powerful love songs",[1] and Roy Carr and Tony Tyler called it "a superb sobber from misery-expert J. W. O. Lennon, MBE. And still one of the most highly underrated Beatle underbellies."[2]

Composition

An anguished love song Lennon wrote to Yoko Ono,[3] Paul McCartney interpreted it 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."[4] Lennon's vocals work their way into screams, presaging the primal scream stylings of the following year's John Lennon/Plastic Ono Band album.[5]
The song is in the key of E and is in 4/4 time during the verse, chorus and bridge, but changes to 5/4 in the pickup to the verse.[6]
