Band Aid 20 is set to raise more than £9m following the biggest-ever single donation to the cause.
Shortly before Christmas, Scottish retail entrepreneur and philanthropist Tom Hunter pledged to match the money raised by sales of the single Do They Know It's Christmas? up to a maximum of £7m.
But in the end, he went even further and promised £6m, which, at a stroke, almost trebled the £3.2m raised through sales of the Christmas number one.
"We've raised way more than we were hoping for," said Band Aid press officer Bernard Doherty.
Hunter also donated £1m to the Make Poverty History campaign. The gifts raised the total awarded by the Hunter Foundation in 2004 to £14m.
Hunter said: "We are making a small contribution to an absolutely massive problem."
Band Aid 20 sold 600,000 copies by Christmas.
