Ms. Mercer won her Tony for a character who appeared in only two scenes. But Marge MacDougall, the comically soused floozy that hero C.C. Baxter picks up in a bar, proved to be a gem of a cameo role for the tall, blonde and brassy actress, equipped as it was with some of bookwriter Neil Simon's best jokes, and one of Burt Bacharach and Hal David's zippiest numbers, "A Fact Can Be a Beautiful Thing." Clive Barnes, writing in the New York Times, called her "a tiny-voiced hustler with a heart as big as a saloon." Ms. Mercer also won a Theatre World Award and a Drama Desk Award for her work.
