Jimmy Fallon has channeled Neil Young before onstage and on his late-night show on NBC, Late Night with Jimmy Fallon. But when have you ever seen him sing alongside the real Crosby and Nash? (Not pictured: Stills)

And yet.

And yet, Fallon posted this photo and wrote this caption: "Crosby, Nash and I salute Miley tonight on Late Night. #partyUSA" Yeah. I think you know what's going on here.


Tune in tonight for Fallon to hear the party for yourself.
