John Lennon - Instant Karma

"Instant Karma! (We All Shine On)" was John Lennon's third solo single on Apple Records, and is notable for two reasons. First, it ranks as one of the fastest-released songs in pop music history, recorded (at London's Abbey Road Studios) the same day it was written, and coming out only ten days later. (As Lennon remarked to the press, he "wrote it for breakfast, recorded it for lunch, and we're putting it out for dinner.")

Second, it was produced by legendary music producer Phil Spector, the first of many solo recordings by The Beatles that Spector worked on through 1970; Lennon may have been trying out Spector for work on the then-dormant Let It Be / Get Back project, which Spector would controversially rework for release that May.
