‘We are the world’: 10 political heavyweights who sang their hearts out (VIDEO)

Possibly the biggest news to come out of David Cameron’s resignation as UK prime minister was the revelation that he had his own exit music: “Doo doo doo doo, right, good.”

The merry tune was hummed by the soon to be ex-Tory leader as he made his way back into 10 Downing Street having announced that he will tender his resignation to the Queen on Wednesday.

Unaware that his mic was still on, Cameron appeared relaxed enough that he managed a little tune, despite his tenure ending prematurely.

But the Conservative PM for Britain since 2010 is not the first politician turned troubadour. In fact many political heavyweights have been caught on tape trying to sing, with some performing better than others.
