Big surprise for the Hobbit’s fans. After a couple of trailers, a sneak peek and several new posters, Warner Bros unveiled the ending song of the upcoming movie  The Hobbit : the desolation of Smaug.

The song entitled “I See Fire” made its debut on YouTube earlier this week. Composed and performed by the young British artist Ed Sheeran, the track will appear in the film’s end credits. “I See Fire” is the singer’s first solo song in two years. Through a series of tweets, Sheeran explained how the recording happened, sharing he played all of the instruments “I got the chance to produce and play all the instruments on it apart from the cello. Managed to learn violin for a day, hope you all dig it”. Then he thanked the film’s director Peter Jackson and the production for the chance to be a part of the film which is scheduled for US release on 13 December.

The full soundtrack composed by Howard Shore will be released December 10 but is already available to pre-order on Amazon and iTunes.
