Olly Alexander and Sir Elton John wowed viewers at the Brit Awards with a dramatic version of Pet Shop Boys' 'It's A Sin'.
The Years And Years frontman, 30, and the 'Rocket Man' singer-songwriter, 74, were joined on stage by drag queens and performed against a backdrop of multi-coloured strobes.
Their version of the 1980s hit was inspired by the Channel 4 TV series of the same name, which stars Alexander and explores the HIV/Aids crisis in 1980s London.
A single of the track is being released to raise money for the Elton John Aids Foundation, and Sir Elton's husband David Furnish appeared before the performance to highlight its work.
Fans were quick to celebrate the performance online.
