A highly-anticipated documentary about late singer Amy Winehouse has premiered in London, where friends and fellow musicians paid tribute to the six-time Grammy Award winner.
The film Amy follows the Rehab singer's life and death in 2011 from alcohol poisoning.
First shown at the Cannes Film Festival, it drew criticism from her father Mitch Winehouse, who has called it misleading. Its makers disagree, saying they conducted around 100 interviews for it.
