How does a Nuyorican Genius who sells out arenas with his keenness end up writing music for intergalactic cantinas? J.J. Abrams told the story on Tonight: The director was seeing Hamilton with his son a few months ago when Lin-Manuel Miranda (who wasn't performing; it was a Javier Muñoz night) simply walked up to him and volunteered his services. It was maybe a joke, but — wait for it — they really did need someone to write a new cantina song. And so, with Abrams as his right-hand man, Miranda dropped everything and penned a song. No one's heard it yet, but we're sure when we do, it will blow us all away.
Miranda later confirmed the news on Twitter:
We did. Worked on it between 6pm & 7:30 on 2 show days for the past 2 months. JJ is the best. Can't wait to see. https://t.co/pPYu8nRsxI— Lin-Manuel Miranda (@Lin_Manuel) December 1, 2015
