Langella went over to a friend's house for lunch in Osterville, Mass. and discovered that also on the guest list were the president, Jacqueline Kennedy, Noel Coward, and Fred Astaire's sister Adele. When Coward began singing and accompanying himself on the piano, Astaire and John F. Kennedy started to dance. "His face was blissfully silly as he feigned a nightclub entertainer and tried to mirror Adele's moves," Langella wrote. "Before boarding the helicopter the President said to me: 'What do you think, Frank? Should I keep my day job?'"
