On John Oliver's show, musicians demand politicians stop using their songs - CNET

So on Sunday's "Last Week Tonight," John Oliver brought them together for a sort of "We Are The World. Get Your Tiny Hands Off Of Our Songs" performance.

This is a serious situation, said Oliver.

Why, when Republican candidate Scott Walker used a song from the Dropkick Murphys, they tweeted back at him: "We literally hate you."

So here were Usher, Michael Bolton, Heart, Sheryl Crow and many others to sing "Don't Use Our Song."

The song explains that politicians should ask for permission -- which they likely won't get.

Worse, often these political types just hear the name of the song and don't listen to the actual lyrics.

Ronald Reagan, for example, used Bruce Springsteen's "Bo In The USA," in the belief that it was a positive anthem, rather than a lament about Vietnam.
