Watch Amy Winehouse recording her classic song Back To Black (Video)

Unseen footage of Amy Winehouse recording her most famous song Back To Black has been released from the chronicle about her life.

Filmmaker Asif Kapadia, the Bafta-winning director of brilliant documentary Senna, has received criticism from the late singer's family over some of the content of Amy. But the biopic is proving to be a huge hit after breaking a UK box office record in its opening weekend. The new video features the late singer in the studio with producer Mark Ronson in 2006, who is in the film talking fondly of his former friend and music partner. He said: "That first day she wrote it (Back To Black), all the lyrics and the melody in two or three hours." Watch here. https://www.youtube.com/watch?v=3su4q5fVGQg
