Content:  "Mary Had a Little Lamb" was released as a single on 12 May 1972 in the UK, moved back from its original planned date of the 5th. The record was released in the US on 29 May. On 25 May, the band mimed a performance of the song for BBC TV's Top of the Pops TV show. The song was attacked by several contemporary rock critics, with one commenting that McCartney had "fallen to tripe" of this genre. However, some critics suspected this immediate change in musical direction to be a deliberately ironic musical manoeuvre. Cash Box said of it that "the nursery rhyme we all know and love gets a bouncy treatment." It reached the top 10 in the UK, peaking at number nine. Some US radio stations also played the pop/rock B-side, "Little Woman Love". Apple Records in the US even revised the picture sleeve for the single to credit both sides by name (see reverse cover), but the single still failed to rise above number 28 in the US.

Content:  At the time, some observers such as Roy Carr and Tony Tyler of New Musical Express presumed the song was recorded by McCartney in response to the BBC ban of his previous single, the political "Give Ireland Back to the Irish", but McCartney has denied this, saying that it was a sincere effort to write a song for children. In fact, the song was written before "Give Ireland Back to the Irish", as a demo of the song can be heard during an interview recorded for radio station WRKO in December 1971.

Content:  The nursery rhyme was first published by the Boston publishing firm Marsh, Capen & Lyon, as a poem by Sarah Josepha Hale on May 24, 1830, and was possibly inspired by an actual incident. As described in one of Hale's biographies: "Sarah began teaching young boys and girls in a small school not far from her home [in Newport, New Hampshire]...It was at this small school that the incident involving 'Mary's Lamb' is reputed to have taken place. Sarah was surprised one morning to see one of her students, a girl named Mary, enter the classroom followed by her pet lamb. The visitor was far too distracting to be permitted to remain in the building and so Sarah 'turned him out.' The lamb stayed nearby till school was dismissed and then ran up to Mary looking for attention and protection. The other youngsters wanted to know why the lamb loved Mary so much and their teacher explained it was because Mary loved her pet. Then Sarah used the incident to get a moral across to the class: And you each gentle animal, In confidence may bind, And make them answer to your call, If you are always kind."
