Video: Cassetteboy—Emperor's New Clothes Rap

Here's British prime minister David Cameron and other politicians unlike you've ever seen them before.

It's promoting a new film by Russell Brand and Michael Winterbottom called The Emperor's New Clothes.

The title comes from Hans Christian Andersen's tale about an emperor who walks the streets in an invisible suit, only to be exposed by a child who declares that the king is actually naked.
