The theme music was composed by Simon May and performed by his orchestra. Executive Leslie Osborne secured a co-writer credit, but in reality did not contribute to the composition. After series one, Don Black was commissioned to write lyrics for the theme; May had suggested the title "Almost There", which Black changed to "Always There". The song was recorded by Marti Webb, and reached number 13 in the UK singles chart. The upbeat variation of the theme, "Barracuda", was used over the show's end credits in 1987–1990, and was a "re-visitation" of a section of May's song "Believe" for his musical "Smike".
