Twiggy has been tapped to play famed actress Gertrude Lawrence in the Bay Street Theatre's biographical revue Noel & Gertrude this summer. The show, which will run July 15 to Aug. 2, looks at the relationship between actress Lawrence and playwright and actor Noel Coward. The Coward role has not been cast. Leigh Lawson will direct.

Preceding Noel & Gertie on the Sag Harbor, Long Island, theatre's 1998 schedule is Horton Foote's new play A Coffin in Egypt (June 17-July 5). The one-person play about passion, infidelity and murder will star veteran actress Glynis Johns (A Little Night Music), in her first visit to BST. The director is Leonard Foglia.

Opening the season is Bob Kingdom's Elsa Edgar (May 22-June 7), in which Elaine Stritch (A Delicate Balance) will play, in separate acts, social doyenne Elsa Maxwell and, incredibly, FBI director J. Edgar Hoover. Kingdom starred in his own The Truman Capote Talk Show at the theatre in 1995. Bay Street producer Murphy Davis directs.

No casting has been announced for the Joe Mantello-directed Terrence McNally-Jon Robin Baitz collaboration House, which will end the Bay Street season. The play concerns a couple buying a house from another couple. Act one, by Baitz, follows the sellers; act two, by McNally, the buyers. McNally, Mantello and Baitz have all worked at Bay Street before.
