Dance-Floor Diplomacy, 1976
Two hundred years after the U.S. declared its independence from Great Britain, the American President danced with the Queen of England. In town for the U.S. bicentennial, Queen Elizabeth II and Prince Philip were the guests of President and Mrs. Gerald Ford in July 1976. First Lady Betty Ford wrote in her memoir that "the Queen was easy to deal with" and "If I hadn't kept mixing up Your Highness and Your Majesty (he's His Highness, she's Her Majesty) I'd give myself four stars for the way that visit went off." As for the dancing, there don't appear to be any reports of President Ford falling or stepping on the Queen's feet. Of course, the U.S. Marine band probably shouldn't have started playing "The Lady Is a Tramp," though it's a great song, with the Queen on the dance floor.
