Adele's 'Skyfall' Theme: What We've Heard So Far

Three days ahead of its global premiere, fans can get a 90-second taste of Adele's sultry 'Skyfall' theme.

Three days head of its scheduled premiere, fans can get a sneak peek at Adele's theme for the upcoming James Bond film "Skyfall," in the form of a 90-second snippet that leaked Tuesday (October 2).

And really, that's all you need to realize the song is not only a welcome return to the classic Bond themes belted out by Shirley Bassey ("Goldfinger," "Diamonds Are Forever," "Moonraker"), but a move away from the pop-tinged numbers that have come to define the franchise's past two decades (Madonna, Garbage and A-Ha, we're looking at you).

Co-written and produced by Paul Epworth, and recorded at London's iconic Abbey Road studios, the "Skyfall" theme is everything you'd expect from Adele: Classy and sultry, full of stirring strings — courtesy of a 77-piece orchestra — and smoky vocals. It is dangerous yet refined ... kind of like 007 himself. Though, to hear Adele tell it, there was a moment where she doubted even she could pull the thing off.

"I was a little hesitant at first to be involved with the theme song ... there's a lot of instant spotlight and pressure when it comes to a 'Bond' song. But I fell in love with the script and Paul had some great ideas for the track, and it ended up being a bit of a no-brainer," Adele said in a statement on Monday. "When we recorded the strings, it was one of the proudest moments of my life. I'll be back combing my hair when I'm 60 telling people I was a Bond girl back in the day."

Quite simply, we can't wait to hear the full thing when it premieres on Friday (October 5) at precisely 0:07 London time (which is 7:07 p.m. ET for us folks here in the states), in honor of the 50th anniversary of the release of the first Bond film, "Dr. No." That date has also been declared "Global James Bond Day."
