"Six O'Clock" is a song by English rock musician Ringo Starr from his 1973 album Ringo. It was written by Starr's former Beatles bandmate Paul McCartney and the latter's wife, Linda, who also participated in the recording of the song. It was the first time McCartney and Starr had worked together since the Beatles' break-up in 1970. Their collaboration reflected an easing of the tensions that had existed between the two musicians for much of that period.
