Geldof asks people to delete and download Band Aid 30 track again

Bob Geldof has urged people to delete and re-download the Band Aid 30 single.
The Boomtown Rats frontman is pleased 'Do They Know It's Christmas Time?' single - which is raising money to fight Ebola in West Africa - has topped the charts in 61 countries after selling over 300,000 digital copies in a week, but is concerned the falling price of music means it won't make as much money as the 1984 original, which made £8m for famine relief thanks to sales of 3.7 million.
