Lin-Manuel Miranda surprises a fan with her very own 'Hamilton' song

Lin-Manuel Miranda surprised a lucky fan when he dropped The Tonight Show Starring Jimmy Fallon. The Tony Award winner made up a song about the fan, Hamilton-style!

Jimmy Fallon occasionally does a bit in which audience members have songs sung about them by The Roots. And the show took it one further by having Miranda sing one of the songs.

Fallon simply told Miranda, “Her Broadway show would be The Sassy Life. And she would love to be played by Adele.”

With the music of the Hamilton song “Alexander Hamilton” accompanying him, Miranda ad-libbed a song about Olivia.

Miranda sang, “How does a sweet, super sweet sweeter than Sweet’N Low and Stevia grow up to be a sassy gal, Olivia? Oh yeah — I’ve loved her ever since she showed up like Adele, wearing those floral prints.”

The audience loved his performance, especially Olivia.

The Tonight Show Starring Jimmy Fallon airs weeknights at 11:35 p.m. on NBC. Watch clips and full episodes of The Tonight Show free on Yahoo View.
