It finally happened. The real Neil Young finally performed with Jimmy Fallon as Neil Young in an epic “Tonight Show” duet.

This is not Young’s first appearance on “The Tonight Show,” but it is his first time sitting down for a song with the fake version of himself that Fallon has been busting out for years, starting on “Late Night.” The call was “Old Man,” Young’s 1972 hit off the album “Harvest.” Watch above.

Below, Young says he’s seen Fallon’s impression of him before and always thought it was really good. He then jokes, “This is the most I’ve been on TV ever.”

Young also has a critique of Bradley Cooper’s air guitar skills when Cooper was pretending to be Young in a lip sync battle on “Tonight”: “He played one of Danny Whitten’s parts like it was my part.” For shame, Cooper.

Finally, Young performs his new song “Who’s Gonna Stand Up?,” which he debuted last fall. No doubt about it, the 69-year-old can still definitely rock.
