Bruce Springsteen sings 'Whip My Hair' with 'Neil Young'

I don't know whether to laugh or cry that The Boss is actually singing Willow Smith's song on Jimmy Fallon's late-night show, but I'm leaning toward the latter. Springsteen was the musical guest on the show this

week, and he got roped into covering "Whip My Hair" with a Neil Young-ified Fallon. If there's one thing to come away with after watching this vid, it's that Fallon's got the whole Neil Young shtick down pat.
