Focus THEATRE GOES ON tour at the end of August with their latest production, Marsha N orrman's 1983 Pulitzer-prize-winning 'Night, Mother, a play about two women dealing with the decision of one of them to commit suicide before the night is out. Jessie the daughter (Deirdre O'Connell), is determined to go gently into that good night; Mama (Ena May), by contrast: means to go screeching when her time comes. Their clash has for its immediate context the simple activity of putting the house in order. Its larger context, and the interpretation of the play, are more difficult to determine.
