The Beatles - Get Back

"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. It was the Beatles' only single that credited another artist at their request.
