Performed as part of the mystery plays, the 'Coventry Carol' is from the Pageant of the Shearman and Taylors and tells the story of the Slaughter of The Innocents.

A copy of the manuscript survived a fire in Birmingham Library in 1879 by sheer chance. Musician Ian Pittaway describes seeing the play in the ruins of Coventry cathedral in the 1980s - the drama was so powerful it still moves him to tears.

The carol was sung on Christmas Day in 1940 in a live broadcast to the Empire just six weeks after the bombing of Coventry that destroyed the city's cathedral.

Journalist Donna Marmestein tells of how the carol transformed how she felt about loss in her family.

Composer and performer Tori Amos describes what inspired her cover version of the song. Amy Hanson from the Small Steps Charity talks about how much her mother loved the carol. The children from the school her charity supports in Kenya sing their version of the song.

Roxanne Burroughs explains about how her daughter Kaitlyn came to have the carol sung at her funeral.

The soloist is Samantha Lewis; early music is from The Night Watch; Reading Phoenix choir and Southern Voices sing the carol and the children's choir is from the Rehabilitation centre Immanuel Afrika in Nairobi, Kenya.
