Our hopes went up when we heard David Crosby and Graham Nash were going to appear on Late Night with Jimmy Fallon. The reclusive Neil Young is a frequent performer on Fallon's show, although it's strange we've never seen the host actually introduce the rock legend, and it would be great to hear CNY once again.

Crosby, Stills, Nash and Young haven't toured for five years, but Crosby and Nash are wrapping a U.S. tour and head to Europe in the fall, and Buffalo Springfield (with Stills, Young, Richie Furay, Rick Rosas and Joe Vitale) is supposed to reunite and play a few gigs this fall.

Sure enough, Neil showed up Wednesday night (while most of you were probably watching the Phillies' 19-inning marathon), and sang a trio with Nash and Croz. It was a funny song-selection, Miley Cyrus' "Party in the U.S.A.," but it was still nice to hear the old boys harmonize again. Here's the video.

And, wouldn't you know it, Fallon and Young once again did not appear together on stage.
