Late-night television took a "Fancy" turn Monday when Jimmy Fallon's cover of Iggy Azalea's hit song prompted a Crosby, Stills, Nash and "Young" reunion on "The Tonight Show."
First things first, Fallon's impersonation of Neil Young is the "realest."
The host has donned the cowboy hat and harmonica multiple times in the past for folk-rock renditions of other pop favorites such as "Whip My Hair" and the "Fresh Prince of Bel-Air" theme, and was even joined by Graham Nash and David Crosby for a performance of "Party in the U.S.A."
It only makes sense that Fallon would take advantage of the trio's appearance to promote their forthcoming live box set "CSNY 1974" and tour by taking on the reigning Billboard chart-topper while in character as their elusive bandmate.
For the purists, Crosby, Stephen Stills and Nash also performed "Teach Your Children" on the show.
