On October 19, 1814 lyrics from Francis Scott Key's poem "Defence of Fort McHenry" set to the tune of "To Anacreon in Heaven" were performed onstage at the theater; it was so enthusiastically received that the performance was repeated for several nights afterward. As the song – now known as The Star-Spangled Banner – gained in popularity, it was accompanied by an illuminated scene of the siege on Fort McHenry.
