David Cameron also claimed to have played a part in the success of Mumford And Sons in the United States after getting them on the bill for a White House reception. He said:
"When Barack Obama said 'we're going to have a bit of a party for you at the White House when you visit, who do you want to be playing there?'.
"I said 'well there's this small band that I'm quite keen on and my wife's quite keen on - I'm not sure you will have heard of them - they're called Mumford And Sons'. And if only I had accepted a percentage, I'd be a lot better off."
