‘Don’t Cry Baby’ is a brief ad-libbed recording by Paul McCartney.
It was taped in early 1970 and consists of the infant Mary McCartney crying, followed by Paul saying: “Don’t cry, little baby. Don’t cry. Daddy’s gonna play you a lullaby.”
The piece was released in 2011 as part of the Archive Collection reissue of McCartney, where it segued into ‘Oo You’.
