the hope that Guare would convince him to write the lyrics for a musical version of The Exception and the Rule; according to Robbins, Bernstein would not work without Sondheim. When Sondheim agreed, Guare asked: "Why haven't you all worked together since West Side Story?" Sondheim answered, "You'll see". Guare said that working with Sondheim was like being with an old college roommate, and he depended on him to "decode and decipher their crazy way of working"; Bernstein worked only after midnight, and Robbins only in the early morning. Bernstein's score, which was supposed to be light, was influenced by his need to make a musical statement. Stuart Ostrow, who worked with Sondheim on The Girls Upstairs, agreed to produce the musical, initially titled A Pray by Blecht, then The Race to Urga. An opening night was scheduled, but during auditions Robbins asked to be excused for a moment. When he did not return, a doorman said he had gotten into a limousine to go to John F. Kennedy International Airport. Bernstein burst into tears and said, "It's over". Sondheim later said of this experience: "I was ashamed of the whole project. It was arch and didactic in the worst way." He wrote one and a half songs and threw them away, the only time he ever did that. Eighteen years later, Sondheim refused Bernstein's and Robbins's request to retry the show. Sondheim lived in a Turtle Bay, Manhattan brownstone from his writing of Gypsy in 1959. Ten years later, he heard a knock on the door. His neighbor, Katharine Hepburn, was in "bare feet – this angry, red-faced lady" and told him "You have been keeping me awake all night!" (she was practicing for her musical debut in Coco). "I remember asking Hepburn why she didn't just call me, but she claimed not to have my phone number. My guess is that she wanted to stand there in her bare feet, suffering for her art". 1970–1981: Collaborations with Hal Prince After Do I Hear a Waltz?, Sondheim devoted himself solely to writing both music and lyrics for the theater – and in 1970, he began a collaboration with director Harold Prince resulting in a body of work that is considered one of the high water marks of musical theater history, with critic Howard Kissel writing that the duo had set "Broadway's highest standards".
