“Diamonds Are Forever”, the title song, was the second James Bond theme to be performed by Shirley Bassey, after “Goldfinger” in 1964. Producer Harry Saltzman reportedly hated the song, and only the insistence of co-producer Cubby Broccoli kept it in the film. Saltzman’s major objection was to the sexual innuendo of the lyrics. Indeed, in an interview for the television programme James Bond’s Greatest Hits composer John Barry revealed that he told Bassey to imagine she was singing about a penis. Bassey would later return for a third performance for 1979′s “Moonraker.”
The original soundtrack was once again composed by John Barry. This was his sixth time composing for a James Bond film. The song has subsequently been sampled by rapper Kanye West in the track Diamonds from Sierra Leone. It was also used by hip-hop group Dead Prez on the song “Psychology” from Let’s Get Free.
