Question: How many cast members did Line of Duty when it premiered on BBC2? Passage 1:The music for the film was composed by Barry De Vorzon and Perry Botkin Jr.. Their score for the movie included an instrumental selection titled "Cotton's Dream", which was later rescored to become the theme song of the soap opera The Young and the Restless; this was produced by Columbia's television division, now Sony Pictures Television. The soundtrack for the film also includes the movie's theme song, performed by The Carpenters. In late July or early August 1976, when ABC's sports summary program Wide World of Sports produced a montage of Romanian gymnast Nadia Comăneci's routines during the 1976 Summer Olympics and used "Cotton's Dream" as the background music, the song gained more popularity and was subsequently released in a re-edited and lengthened form as "Nadia's Theme", a title under which it became best known. (Comăneci herself never performed her floor exercises using this piece of music, however.) De Vorzon and Botkin Jr. also wrote lyrics for "Cotton's Dream" but no vocal version of it was known to have charted .
