Jimmy Fallon "Party in the USA" (performed as Neil Young with David Crosby and Graham Nash)
Following his amazing rendition of Neil Young performing Willow Smith's "Whip My Hair," Jimmy Fallon continues his amazing series of pop culture-referencing viral videos on Late Night, with a cover of Miley Cyrus' "Party in the USA," once again taking on Young's identity.

Once again, Fallon's Young impression is completely spot on and his WTF?-worthy song choice would have carried the sketch on its own. Instead, the late night host kicks things up a notch with a guest appearance from the real David Crosby and Graham Nash.

Check out the unbelievable clip below.
