Band Aid 30's Do They Know It's Christmas?, which features a host of stars, stormed to the top of the singles chart today.
The reworked version of 'Do They Know It's Christmas?' features stars including One Direction, Bono and Ellie Goulding, and is expected to raise millions to help fight the Ebola crisis in West Africa.
Emeli Sande was one of those who questioned the lyrics which had been changed to reflect the Ebola crisis in west Africa.
Bob Geldof has said he is "overwhelmed" after Band Aid 30 single Do They Know It's Christmas reached number one in 48 countries on the iTunes charts.
The song has already become the fastest-selling single of 2014, with 206,00 copies at the latest estimate since its release on Monday morning.
"We're all sitting here overwhelmed and speechless," Geldof said. "So many people will now find some comfort this Xmas because of you. It makes it all worthwhile doesn't it?"
The former Boomtown Rats singer said he now aimed to beat the record set by the first Band Aid single.
Emeli Sande has said the Band Aid song needs rewriting and apologised if the latest version "caused offence".
Bob Geldof premiered the video for the latest Band Aid single on X Factor, featuring a powerful opening segment referencing the Ebola virus.
