This standalone Christmas song was released by the British alternative rock band Coldplay on December 1, 2010, as a digital download. According to the band's website, the mid-tempo number is "in the key of G."
Mat Whitecross directed the video for the song, which was filmed at the South Bank of River Thames in London. The band are seen performing the song on a small theater-inspired stage with red velvet curtains. "The idea for the video was like a magical, surreal theater show with loads of tricks packed in," frontman Chris Martin said.
A trio of Elvis Presley impersonators are seen playing violins - they are the band's former manager Phil Harvey, Tim Crompton, the frontman of Coldplay support act The High Wire and comic actor Simon Pegg.
The words above the stage curtain in the video say CREDO ELVEM ETIAM VIVERE. This means "I believe Elvis lives" in Latin.
Two tears roll down Sinead O'Connor's face. toward the end of the video for "Nothing Compares 2 U." They were shed because she associated the song's lyrics of love and loss with her mother, who was killed in a car accident in 1985.
