“Get Back” is a song recorded by the Beatles and written by Paul McCartney (though credited to Lennon-McCartney), originally released as a single on 11 April 1969 and credited to “The Beatles with Billy Preston.” A different mix of the song later became the closing track of Let It Be (1970), which was the Beatles’ last album released just after the group split. The single version was later issued on the compilation albums 1967–1970, 20 Greatest Hits, Past Masters, and 1.
The single reached number one in the United Kingdom, the United States, Ireland, Canada, New Zealand, Australia, France, West Germany, and Mexico. It was the Beatles’ only single that credited another artist at their request. “Get Back” was the Beatles’ first single release in true stereo in the US. In the UK, the Beatles’ singles remained monaural until the following release, “The Ballad of John and Yoko”.
