With a side of briefs:
Hart’s wife Kitty Carlisle (1910-2007) was committed to protecting her husband’s secrets. A socialite, opera singer, stage and film actress and cabaret performer, she was married to Hart for the last fifteen years of his life, and their union produced two children. Although Hart died in 1961 of a heart attack at age 57, she lived for another 46 years, never remarrying. In Steven Bach’s biography of Hart, Dazzler: The Life and Times of Moss Hart (2001), the author revealed that throughout his marriage Hart was a closeted bisexual. Miss Carlisle made no public comment about the contents of the book, but until her death she continued Hart’s own attempt to heterosexualize his life story, despite his physical relationships with literary agent Lester Sweyd. MGM screenwriter Charles Lederer and many of the homosexuals mentioned in Hart’s autobiography. In a 1939 letter written by Hart to Dore Schary (later president of MGM Studios), he wrote the damning words, “We shall once again lay in each other’s arms and taste the sweetness of sin – I love you very much.”
After his death Carlisle sealed Hart’s diaries and prevented access to materials that contained evidence of his sexuality. Nevertheless, Hart’s name cropped up on lists of bisexuals by Yamaguchi Fletcher, Adrien Saks and others.
Suffering from writer’s block, manic depression and numerous nervous breakdowns, Hart developed an addiction to psychoanalysis. His therapist, Lawrence Kubie, strongly disapproved of Hart’s gay alliances and pushed him into eventually adopting an entirely heterosexual lifestyle. Kubie was known for “conversion therapy” that resulted in redirecting gay or bisexual patients to heterosexual lives. Kubie saw Hart twice a day and conducted shock therapy once a week. As a result, at age 42, Hart married Kitty Carlisle, an act that greatly surprised most of his friends and associates. After getting married, Hart ended his friendships with many "out" gay men, but Arthur Laurents reported his embarrassment at the wedding reception at Hart’s house in Bucks County, PA, when Hart suggested that the men take all their clothes off when there were no women around. Following a performance by Kitty Carlisle at Bucks County Playhouse in 1948, Hart proudly presented his infant son to the audience, declaring, "Now they won't be able to say I'm gay anymore."
Personal note from your blogger: One of the first professional stage productions I ever saw was a revival of Hart's Light Up the Sky.
