Underworld, Bono, Sinead O’Connor and the lesser-spotted Emeli Sande have all signed up.

Bob Geldof has called on his celeb pals to make a fourth version of the Band Aid charity single ‘Do They Know It’s Christmas’ with the lyrics changed to reflect the Ebola epidemic in Africa.

The new version will be recorded this Saturday and should be available for download on Monday morning, with proceeds going towards fighting the health crisis. Artists confirmed to appear on the record include Bono, Chris Martin of Coldplay, Emeli Sande, Underworld, Sinead O’Connor, Paloma Faith, Foals and Bastille, as BBC News reports.

Versions will also be recorded in France, Germany and the US, said Geldof, hinting: “Think Daft Punk. Think Johnny Hallyday.”

The original song, featuring Bono, Bananarama and George Michael among others, was released in 1984 and sold 3.7 million copies to raise £8 million for famine relief in Ethiopia. The 1989 version was produced by Stock, Aitken and Waterman and featured acts from their pop stable like Kylie Minogue, Jason Donovan and Sonia, while Band Aid 20 in 2004 included Dizzee Rascal, Ms Dynamite and Robbie Williams.

But will they be able to improve on the classic line, “And the Christmas bells that ring there are the clanging chimes of doom”? And how exactly will they squeeze an Ebola reference into “And there won’t be snow in Africa this Christmastime”? Answers on a postcard please.
