Jimmy Fallon Dresses Up As Neil Young, Performs "Old Man" With the Real Neil Young: Watch Now!

Jimmy Fallon and Neil Young performed together on Tuesday evening.

The only thing better than one Neil Young is two Neil Youngs!

The "Heart of Gold" performer, 69, stopped by The Tonight Show on Tuesday, Feb. 3, and met his double in the form of a costumed Jimmy Fallon. The talk show host, 40, has done his best Young impression in the past and dusted off his duds for a repeat performance this week. 

Wearing a tan hat over a wig with a suede jacket, plaid shirt, and faded jeans, Fallon took the stage after being introduced by Steve Higgins as Neil Young. The funnyman strummed a guitar as he sat on a stool and sang Young's 1970s classic "Old Man."

Under a spotlight on a dark stage, Fallon crooned, "Old man take a look at my life / I'm a lot like you / I need someone to love me / the whole day through / Ah, one look in my eyes / and you can tell that's true."

Midway through the performance, he was joined by the legendary musician. The Grammy-winning Young strolled onto the stage in a matching outfit and took the stool adjacent to Fallon's before lending his vocals to the set.

While he opted for a Young classic on Tuesday evening, in the past Fallon has performed as Young while singing modern hits such as Miley Cyrus' "Party in the U.S.A." the theme from Fresh Prince of Bel-Air, and Iggy Azalea's "Fancy."
