In the open title sequence for each Bond film, everybody should know that MGM writes an original song w/ lyrics that has something to do with the title and then they would hire a famous singer to sing the song. Over the years, have been mostly female singers that sung the 007 theme song but sometimes they would get male singers. I remember Chris Cornell of Soundgarden sung the theme song for “Casino Royale”. Madonna already did a theme song, she did the theme for “The World Is Not Enough” and she even had a role in the film too.
It’s been announced by Sam Mendes and MGM that a singer for “Spectre” have already been chosen but nobody’s talking on who it is yet.
I wouldn’t be surprised if the singer is gonna be these 5:
-Lady Gaga/Tony Bennett (with them together)
-Barbara Streisand (she never did a Bond theme yet, surprisingly)
If they’re gonna go for a male singer, they’d go for Tony Bennett, John Legend, Prince or Bruno Mars.
I’m probably gonna be wrong on all of these but these are pretty good guesses. We’ll soon find out who the singer is gonna be for “Spectre”.
