Watch Prince Harry Sing a Bit of King George III's Song at the Hamilton Sentebale Gala

From Town & Country

Before Prince Harry thanked the crowd at tonight's Hamilton gala performance, he delighted the audience by singing a few notes of King George III's song, "You'll Be Back."

"You say..." Prince Harry starts, before the theater erupts in applause and laughter. Watch the clip here:

Creator of the show Lin Manuel Miranda later posted a video of Harry's performance with the caption "King George III’s great-great-great-great-great-great grandson The Duke Of Sussex sang a few bars tonight #HamiltonLDN 👀"

Unfortunately, Harry doesn't finish out the tune, which is something of a Brit pop breakup letter from America's last King to the colonies. Instead, he very earnestly goes on to thank everyone involved in this evening's event, which raised money for his charity Sentebale.

"Ladies and Gentleman, thank you so much," he says. "You have together raised a huge amount of money to change the lives of thousands of children in Bostwana and Lethoso. And through that work that we're going to be doing now, we'll be able to stop the generational hand down of stigma around HIV."

The Duke of Sussex is actually related to King George III multiple times over. George III was both Harry's 6x great grandfather and his 5x great grandfather, among other relations. But clearly Harry doesn't mind that Hamilton pokes fun at his distant relative-this was his second time seeing the production.
