James Bond fans have welcomed Adele's "classic" theme for the latest 007 film after a short clip was leaked online.
The award-winning singer has teamed up with Paul Epworth, who co-wrote and produced her massive hit Rolling In The Deep, to write Skyfall for the new film of the same name.
Fans were given a taste of the track when a 90-second clip appeared on the Soundcloud website but it was removed within hours. The track, recorded at Abbey Road Studios in London with a 77-piece orchestra, was not due to be given its premiere until 0.07am on Friday on Adele's website.
Ajay Chowdhury, from the James Bond International Fan Club, said: "There are three types of Bond song - one is bold, brassy and sexy like Goldfinger, another is reflective and mournful like You Only Live Twice, and the third is anthemic and adventurous like Live And Let Die.
"Adele's song is very definitely reflective and mournful. Co-written by her and Paul Epworth, with an arrangement by Epworth and JAC Redford, this 50th anniversary theme is Bondian but very Adele too.
"It's a beautiful ballad that promises to become a Bondian classic. I can imagine it in the film, underlaid by Daniel Kleinman's titles - Bond fans are in for an aural treat."
Adele has said she was "hesitant" about recording the song. She said: "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 to do it in the end.
"It was also a lot of fun writing to a brief, something I've never done, which made it exciting.
"When we recorded the strings it was one of the proudest moments of my life. I'll be backcombing my hair when I'm 60, telling people I was a Bond girl back in the day, I'm sure."
The film, again starring Daniel Craig as Bond, is to be given its premiere on October 26.
