Broadway singer-actress Barbara Cook, the Candide and She Loves Me soprano in late-career flower again in concerts, will be honored by the New Dramatists at its 53rd Annual Benefit Luncheon May 14.

The "nation's oldest non-profit workshop dedicated to the development of new playwrights" will honor Cook at the annual spring luncheon, which will be held in the Broadway Ballroom of the New York Marriott Marquis. Director Harold Prince will present Cook with her award, and he and Stephen Sondheim will serve as the event's honorary chairs.

Each year, the organization — which was founded in 1949 by Michaela O'Harra in association with Richard Rodgers, Oscar Hammerstein II, Moss Hart, Howard Lindsay and Russel Crouse — salutes an individual who has "made an outstanding artistic contribution to the American theatre." Past honorees include Angela Lansbury, Julie Andrews, Glenn Close, John Kander & Fred Ebb, Neil Simon, Jerry Herman, Stephen Sondheim, Gwen Verdon, Terrence McNally and Arthur Miller.

Cook, cheered for her beautiful soprano voice, received critical hosannas for her recent concerts at Lincoln Center, Mostly Sondheim. The Tony-winning performer, who has starred on Broadway in Flahooley, Candide, The Gay Life, The Music Man and She Loves Me, will sing her Mostly Sondheim evening of songs (written by — or loved by — Stephen Sondheim) in summer dates in New York and Washington, DC.

Tickets for the luncheon are $200, a portion of which is tax deductible. For information, call (212) 757-6960. —By Andrew Gans
