After the abolition in 1968 of theatre censorship in Britain, Travers was for the first time able to write about sexual matters without discreet allusion or innuendo. "The Bed Before Yesterday" (1975) depicts a middle-aged woman discovering the pleasure of sex, to the consternation of some who know her and the delight of others. Joan Plowright played the central character with John Moffatt, Helen Mirren and Royce Mills in the main supporting roles. It received enthusiastic notices and ran for more than 500 performances, far outstripping the original runs of any of Travers's Aldwych farces.
