It's one of the most iconic scenes in the entire "Star Wars" franchise -- and it's getting a callback in "Star Wars: The Force Awakens." Yes, the first new "Star Wars" film in a decade will feature a scene set in a cantina, a nod to the scene in 1977's first "Star Wars" film. But when it came to coming up with a tune to play in the scene, "Force Awakens" director J.J. Abrams revealed to Jimmy Fallon on "The Tonight Show" that he got some help from "Hamilton" and "In The Heights" lyricist/composer Lin-Manuel Miranda.

"I go to see the show ['Hamilton'] with our son, and at intermission, Lin-Manuel Miranda -- who wrote it, conceived it and normally stars in it, he wasn't in it that night -- comes up to me," Abrams told Fallon. "And he says hello, and my mind is blown because he's so brilliant, and he says, 'Hey, if you need music for the cantina, I'll write it.'"

The fact that "Force Awakens" does have a cantina scene had been kept secret and caused Abrams to jokingly wonder if Miranda had obtained inside intel somehow. Abrams explained to Fallon that composer John Williams said he would "rather not write the music for that scene." After that development, Abrams emailed with Miranda and asked if he'd like to be involved -- and Miranda said "I'll drop everything."

The two sent music files back and forth and came up with a song that is in the new cantina scene. Miranda also discussed the writing process on Twitter, saying that he fit in the cantina writing sessions in-between performances of "Hamilton."

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.
