Jimmy Fallon as Neil Young Sings ‘Fancy’ by Iggy Azalea With the Real Crosby, Stills & Nash

Tonight Show host Neil Young….errr…Jimmy Fallon is so perfect leading Stephen Stills, David Crosby, and Graham Nash into a Neil Young-style cover of the Iggy Azalea pop hit “Fancy”. Crosby, Stills & Nash also stuck around for a quick riff on their 1969 Judy Collins tribute, “Suite: Judy Blue Eyes”.
