Harry Styles, George Michael, Sinead O'Connor and Ed Sheeran are among the stars whose vocals will feature in a new "ultimate mix" of Band Aid's Do They Know It's Christmas?
The song will feature on a forthcoming compilation marking 40 years since the original charity single was released, organisers Bob Geldof, Midge Ure and Trevor Horn said.
The original single by the charity supergroup was released in 1984 to raise money for anti-famine efforts in Ethiopia.
Since then, the song has been re-recorded three times to mark the fifth, 20th and 30th anniversaries, with some of the most popular artists from each era taking part.
