Hamilton (musical)

Hamilton was a 21st century musical about the life of United States founding father Alexander Hamilton. The Doctor found the songs from the show to be very hummable and had it stuck in his head for a thousand years. Several of his incarnations, including the Second Doctor and the Tenth Doctor, saw Hamilton.

Alice Obiefune owned the official soundtrack and thought that the songs were "very catchy". She asked the Eleventh Doctor to take her to Hamilton, but he found buying tickets to the show "very distressing" as he kept on "bumping into past selves". They decided to visit the real Alexander Hamilton instead. (COMIC: The Long Con)
