Tonight Show host Jimmy Fallon donned the fedora and harmonica for a Neil Young-style cover of the Iggy Azalea pop hit “Fancy” with the Canadian singer’s sometimes bandmates Stephen Stills, David Crosby, and Graham Nash. Crosby, Stills & Nash also stuck around for a quick riff on their 1969 Judy Collins tribute, “Suite: Judy Blue Eyes”.
