"Moonraker" was the third of three Bond films for which the theme song was performed by Shirley Bassey (following "Goldfinger" and "Diamonds Are Forever"). Frank Sinatra was originally considered for the vocals, and Kate Bush was asked, but she declined. Johnny Mathis was approached and offered the opportunity. However, Mathis—despite having started recording with Barry—was unable to complete the project, leaving producers to offer the song to Bassey just weeks before the premiere date in England. Bassey made the recordings with very short notice and as a result, she never regarded the song 'as her own' as she had never had the chance to perform it in full or promote it first. The film uses two versions of the title theme song, a ballad version heard over the main titles, and a disco version over the closing titles. The song made little impact on the charts, reaching #159, partly attributed to Bassey's failure to promote the single, given the last-minute decision to quickly record it to meet the schedule.
