UPDATE: Stream the show HERE.
Paul McCartney's seventeenth solo album, Egypt Station is out today (9/7), and he's been celebrating its release in NYC. Official Paul McCartney MetroCards have been available at the Grand Central 42nd St subway station for the past few days, Paul himself appeared on Howard Stern, Marc Maron's WTF Podcast, Carpool Karaoke with James Corden, and Jimmy Fallon (more on that in a minute), and he's livestreaming a concert tonight starting at 8 PM from a secret NYC location. Paul dropped a couple of big hints on Fallon last night pointing to Manhattan's Grand Central Station being the location of tonight's show - when Jimmy asked where it was happening, Paul responded, "the album's title is Egypt Station...so there might be a little clue there...station. It might be a grand show, I don't know." Watch video of that below.
UPDATE: NBC NY's Adam Kuperstein is on the scene:
UPDATE 2: other visitors to Grand Central have seen stuff, too:

Paul also performed "Come on to Me" from the new album on Fallon, and took part in a skit surprising people riding the elevators for a tour of 30 Rock. Watch video from all of that, and stream Egypt Station, below.
