Skyfall, the new James Bond theme sung by Adele, has topped the iTunes chart after being released online in the early hours of Friday morning.

It was number one within 10 hours of being released, overtaking last week’s official UK number one Gangnam Style.

The full single was released at 00:07 BST, after a 90 second clip was apparently leaked online this week.

The 23rd James Bond film, Skyfall – Daniel Craig’s third outing as 007 – is released in UK cinemas on 26 October.

Adele ended months of speculation over her involvement on Monday, when she posted a picture on Twitter, featuring the cover page of the sheet music for the Skyfall theme, bearing her name alongside that of longtime producer and co-writer Paul Epworth.

The “dark and moody” theme was intended to echo the narrative of the film.

Skyfall was recorded at Abbey Road Studios in London, and features a 77-piece orchestra.

Adele broke her silence on the track in an official message on the James Bond website 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, I’m sure!”

Adele admitted she was a “little hesitant” about accepting the challenge because of the “instant spotlight and pressure” that came with a Bond song.

But, she said it ended up being a “no-brainer” after she fell in love with the script.
