Conti–who was responsible for the film's score–had originally written the song thinking about Donna Summer or Dusty Springfield, singers he thought "fit the Bond style"
Easton is the only artist to be seen singing the theme song to a Bond movie during its opening titles, as Maurice Binder liked Easton's appearance and decided to add her to the credits. Her seductive appearance in these clips was, according to Roger Moore, sexier than any of the Bond girls, although Easton herself states that the filming process was very unglamorous.
The song was released as a single in 1981, at the same time as the film's launch. It became a worldwide hit, reaching the top 10 in the UK, and top 5 in the US. It remains one of Easton's biggest hits and is included on compilation soundtrack albums.
