Input (English): Passage: Bush starred in the 1990 black comedy film Les Dogs, produced by The Comic Strip for BBC television. Bush plays the bride Angela at a wedding set in a post-apocalyptic Britain. In another Comic Strip Presents film, GLC, she produced and sang on the theme song "Ken". The song was written about Ken Livingstone, the leader of the Greater London Council and future mayor of London, who at the time was working with musicians to help the Labour Party garner the youth vote.Bush wrote and performed the song "The Magician", using a fairground-like arrangement, for Menahem Golan's 1979 film The Magician of Lublin. The track was scored and arranged by Michael Kamen. In 1986, she wrote and recorded "Be Kind to My Mistakes" for the Nicolas Roeg film Castaway. An edited version of this track was used as the B-side to her 1989 single "This Woman's Work". In 1988, the song "This Woman's Work" was featured in the John Hughes film She's Having a Baby, and a slightly remixed version appeared on Bush's album The Sensual World. The song has since appeared on television shows, and in 2005 reached number-eight on the UK download chart after featuring in a British television advertisement for the charity NSPCC.In 1999, Bush wrote and recorded a song for the Disney film Dinosaur, but the track was not included on the soundtrack. According to the winter 1999 issue of HomeGround, a Bush fanzine, it was scrapped when Disney asked her to rewrite the song and she refused. Also in 1999, Bush's song "The Sensual World" was featured prominently in Canadian filmmaker Atom Egoyan's film "Felicia's Journey".In 2007, Bush was asked to write a song for The Golden Compass soundtrack which made reference to the lead character, Lyra Belacqua. The song, "Lyra", was used in the closing credits of the film, reached number 187 in the UK Singles Chart and was nominated for the International Press Academy's Satellite Award for original song in a motion picture. According to Del Palmer, Bush was asked to compose the song on short notice and the project was completed in 10 days.

Output (English): Lyra.
