Hamilton creator Lin-Manuel Miranda stomped his feet in delight after Prince Harry sang a line from the hit musical onstage in Londons West End.

Harry and his wife, Meghan Markle , the Duchess of Sussex, attended a special benefit performance of the show on Wednesday night to raise funds for his Sentebale charity. Harry founded the nonprofit with Prince Seeiso of Lesotho to assist young people affected by HIV in Lesotho and Botswana.

Through that work that were going to be doing now, we will be able to stop the generational hand down of the stigma around HIV, Harry said.

He took to the stage afterward to pay tribute to the cast and crew, and couldnt resist breaking out into song:

Harry then thanked everyone involved in the show, and the audience for taking part in this evenings activities because you have together, raised a huge amount of money to change the lives of thousands of children in Botswana.

Miranda later tweeted about the evening:
