Jimmy Fallon is known as a master impressionist and last night he performed one of his best acts yet. As Iggy Azalea’s hit “Fancy” tears up the charts, Fallon grabbed his acoustic guitar and performed the song on The Tonight Show as folk legend, Neil Young. Fallon was joined by Young’s frequent collaborators David Crosby, Stephen Stills, and Graham Nash to make the performance as authentic as possible.
