Hamilton creator and star Lin-Manuel Miranda is currently in Puerto Rico reprising his lead role in the now-iconic musical for a great cause, and he was recently joined by none other than Jimmy Fallon. Miranda is raising relief money for people who were devastated by 2017’s Hurricane Maria, and Fallon was inspired by Miranda to take The Tonight Show to the U.S. Territory and film a very special episode.

The result is, honestly, really terrific. Conan O’Brien has been doing travel shows like this on Conan for the last few years, so this isn’t necessarily blazing new territory, but Fallon’s move is admirable given that it’s motivated by shedding light on people in desperate need of assistance.

If you missed the Tonight Show episode, they’ve put a number of clips online. First up, we get to see Miranda back on the Hamilton stage performing “Story of Tonight”—with a twist! Fallon joins the proceedings towards the end of the song, switches up the lyrics, and it morphs into the intro for The Tonight Show Starring Jimmy Fallon. It’s pretty darn delightful.

There’s also a full interview with Miranda conducted on the Hamilton stage, as well as a really incredible video performance of Fallon, Questlove, and Black Thought performing “MIA” on the streets of Puerto Rico with Bad Bunny. It starts small and intimate, but then it explodes into this tremendous single-take performance.
