The song was written about Craven's eldest daughter Mollie, born in 1992, and the lyrics talk about the joy of motherhood and the lifelong duties to it.

[1] "Mollie's Song" was released as a two-part CD single.

CD 2 included the b-side only track "Call Me", and both CD1 and CD2 included as a b-side the traditional lullaby "Hush Little Baby", which was recorded for an episode of the BBC TV programme Challenge Anneka, broadcast on 23 September 1992, in which Anneka Rice organized the release of an album (titled Tommy's Tape), whose royalties would be donated to Tommy's Campaign, for research into premature births at the Children's Intensive Care Unit in St Thomas' Hospital in London.

The tape was produced by George Martin and Craven's recording of the lullaby was included in it.

All the royalties from the sale of the "Mollie's Song" single were also donated to Tommy's Campaign.
