For hay fever, the allergy, see Hay fever.Hay Fever is a comic play written by Noel Coward in 1924 and first produced in 1925 with Marie Tempest as the first Judith Bliss. Best described as a cross between high farce and a comedy of manners, the play is set in a British country house in the 1920s, and deals with the four eccentric members of the Bliss family and their outlandish behaviour when they each invite a guest to spend the weekend. The self-centred behaviour of the hosts finally drives their guests to flee while the Blisses are so engaged in a family row that they do not notice their guests' furtive departure.
