Prince Harry made a "Hamilton" audience and cast go wild on Wednesday night just by singing two words: "You say."
Harry belted out the opening line of "You'll Be Back" while attending a charity performance of the hip-hop musical at the Victoria Palace Theater in London's West End. As you can see in the video below, the audience and stars of the production -- including creator and original star Lin-Manuel Miranda -- absolutely loved it, even though Harry refused to continue.
"That's definitely not going to happen," Harry said, then pointed at Miranda and added, "He did try, but I said, 'no.'"
Harry was on stage to thank everyone for participating in the gala fundraiser for Sentebale, a charity that supports the mental health and wellbeing of children and young people affected by HIV in Lesotho and Botswana. It's a cause Harry's mother, Princess Diana, championed before she died 21 years ago.
The prince's brief performance came after Miranda introduced Harry to the stage by pointing out he's the sixth great grandson of King George III, portrayed as an antagonist in the musical about the life of American revolutionary leader Alexander Hamilton.
"I was on my honeymoon when I thought, you know, it would be funny if I had King George in the show," Miranda said. "Smash cut to 2018, and I am sitting next to his sixth great grandson. Ladies and gentleman, the Duke of Sussex."
