First, HOLY CHRIST MAN THAT SOUNDS AWESOME.

The best part is set up by this:

“They have a stage set up with just instruments: drums, mics, guitars, bass, keyboard, but no band,” Fallon said. “Just a set up in case anyone wants to get on stage and jam.”

Second, pretty much only Fallon could tell that story and not come off like an asshole. You still get the idea that he cannot believe his immense good fortune. For him, part of it are just a story about his friends (when he references cast members), but in the rest of it he’s just as starstruck as anyone else would be.

(To be fair, Seth Meyers gave a shorter recap, and he’s equally amazed and charming — and points out what Fallon kind of buries, which is Jimmy’s key role in making the jam happen.)
