Jimmy Fallon Impersonates Neil Young, Sings

Jimmy Fallon is the realest—even when he's impersonating Neil Young! On Monday's Tonight Show, the late-night host back brought his impersonation of the Grammy-winning singer for a cover of Iggy Azalea's "Fancy" with Crosby, Stills & Nash. The folk supergroup teased Monday night's appearance on Twitter, touting a tune-in to to their Tonight Show performance as part of a reunion. And while the real Young wasn't able to be there, Fallon did a pretty good job filling in for one of music's greatest.
