Leave it to Jimmy Fallon to take the hot song du jour and turn it into a hilarious cover. The host took to the mic on his show last night to do a Neil Young rendition of Willow Smith's "Whip My Hair" with The Boss as his backup. The song starts off with Fallon gloomily crooning about his "haters," then midway through a ragged Bruce Springsteen joins in for the chorus. It's a brilliant collaboration, and honestly, the cover actually sounds pretty good! Watch the video after the jump.
