The young New York City theatre troupe, The Keen Company, will present as only its third venture a revival of John van Druten's seldom-produced The Voice of the Turtle. The mounting, directed by Carl Forsman, will run Sept. 9-30, at the Blue Heron Theatre.

The Keen Company hit the ball out of the park with its very first offering, the New York premiere of Conor McPherson's The Good Thief, starring Brian D'Arcy James and staged by Forsman. The show transferred to an Off-Broadway commercial run and won James an Obie Award. It has since played the Garter Lane Theatre in Waterford, Ireland.

In Turtle, Elizabeth Bunch stars as Sally Middleton, who has sworn off love since an affair with a married producer went south. That is, until her best friend Olive (Megan Byrne) leaves her alone with Sergeant Bill Page (Nick Toren). Turtle originally opened on Dec. 8, 1943, and had a very long run (1,557 performances), though it is little remembered today. Margaret Sullivan starred as Sally under van Druten's direction.

Van Druten's other plays include The Distaff Side, Old Acquaintance, I Remember Mama and, perhaps most famous, I Am a Camera. He was also a well-known director. One of his last assignments was the staging of The King and I, which bowed on Broadway the same year as Camera.

Tickets are $15. The Blue Heron is located at 123 E. 24th St. For information, call (212) 560-7284. —By Robert Simonson
