PalJoey said: "Having felt both Arthur's love and Arthur's venom, I can say that the crux of it is in Sondheim's words "Arthur is the master of the imagined slight." Once, in a classroom setting, SS told us that he loved Arthur and loved collaborating with Arthur, but that periodically he and Arthur would not speak for several years.
Each time that would happen, SS went on, Arthur would say it was because SS had said or done "something unforgivable."
SS then paused and smiled ironically. "Which is funny," he said, "since Arthur says and does unforgivable things to people every day.""
Good lord, was Arthur in the room when he said all that?
Oh yes, and there was the article from years ago where he claimed to have entirely fixed WICKED for Schwartz and Holtzman, but no one credits him.
