It’s always a treat when Jimmy Fallon busts out his Neil Young impression for late-night TV, but it was even more exciting on Monday (July 7) when he was joined by Young’s fellow band members David Crosby, Stephen Stills and Graham Nash for a surprise “Tonight Show” performance.

And what better song to have them sing than a cover of current hit “Fancy” by pop star Iggy Azalea? It’s fantastic. Below, watch Crosby, Stills & Nash perform as the musical guests.

The next logical step is that Fallon gets the actual Neil Young to do a duet with his “Neil Young”, right? Fingers crossed.
