Neil Young has a lot of things going on, between new albums and his music player project. Still, that doesn’t mean the man doesn’t know how to have a bit of fun every once in a while. Young stopped by The Tonight Show Starring Jimmy Fallon, ostensibly to promote his new album Storeytone. Of course, Fallon has a killer Neil Young impression that he pulls out on occasion, and with the man there, he couldn’t help himself. Neither could Young, who sat in with his doppelganger for a performance of “Old Man.” Young also came back to play his socially conscious single “Who’s Gonna Stand Up” with some help from The Roots. You can watch both performances below.
