Reading the script for Caryl Churchill's 1979 play about sex and love is a special workout for the imagination. First, she asks you to imagine characters whose sexual identities and alliances shift constantly. Then she asks you to imagine that most of the characters make an impossible leap in time, from colonial Africa in the Victorian age to contemporary Britain. Lastly, she asks you to imagine some of the male characters played by women and some female characters played by men. Churchill likes to get things good and mixed up so all the audience's preconceptions about gender, romance, and "lifestyle" are scrambled, neutralized, and possibly even rebuilt. The title refers to the state of orgasmic and emotional bliss that everyone in this play seems to be striving for so desperately.
