Band Aid's reworked Do They Know It's Christmas? has become the U.K.'s fastest-selling single of the year in just two days.

The charity anthem, featuring the voices of One Direction, Bono and Ed Sheeran, among others, is poised to return to the number one spot on Sunday (23Nov14).

The track was recorded in London on Saturday (18Nov14) and released the following day after debuting on Tv talent show The X Factor. Fans have already snapped up over 206,000 copies of the single - that's more than the 200,000 who picked up copies of the original track in its first two days on release back in 1984.

In 2004, the Band Aid 20 version sold 297,000 copies in its first week.

The new version passes Clean Bandit's Rather Be as the fastest-selling single of 2014. That sold 163,000 in its first week in January (14).

Thrilled Bob Geldof, who has masterminded all the Band Aid get togethers, says, "We are overwhelmed by the support that you have given us so far. What an amazing country this is. We're all sitting here overwhelmed and speechless. Let's keep leading the world on this. Let's try and beat the record set by the first Band Aid. It's so cool living in this country at times like this."

The original track raised millions for famine relief in Africa. Sales from the new version will benefit volunteer groups tackling the Ebola pandemic in West Africa.
