Harry Groener will play Noel Coward to Twiggy's Gertrude Lawrence in Sheridan Morley's If Love Were All, a new revue which examines the relationship between Lawrence and her friend and frequent co-star, playwright Coward.

The production will begin performances at the Lucille Lortel Theatre on May 18 and open on June 10. Leigh Lawson will direct. Niki Harris is the choreographer and Tony Walton provides the sets.

If Love Were All, by Sheridan Morley, has been previously performed under the title Noel & Gertie. The show had its U.S. debut several years ago at the York Theatre and was revived last summer at the Bay Street Theatre in Sag Harbor, Long Island. Twiggy's co-star at that time was James Warwick, who starred in the Peter Hall-directed Broadway revival of An Ideal Husband.

Lawrence was perhaps playwright Coward's most famous interpreter, appearing in many of his plays, including London Calling!, Tonight at 8:30, and, famously, Private Lives.

Twiggy acted in Private Lives in a London staging two years ago. However, in theatrical circles, she is still best known for her Broadway turn in George Gershwin musical My One and Only, in which she co- starred with Tommy Tune. Groener is best known for his many years as the star of the Broadway musical Crazy for You.

Morley is the London theatre critic for the International Herald Tribune and for the Spectator, and has appeared frequently on British television and on the cabaret stage. He has written more than a dozen books on entertainment personalities, including his father, actor Robert Morley. He's also a correspondent for Playbill On-Line.
