The York Theatre Company, which is located in the Theater at Saint Peter's Church in the Citicorp Center (Lexington at 54th Street), will present producer Cameron Mackintosh with the 12th annual Oscar Hammerstein Award at a June 3 benefit.

The award commemorates lifetime achievement in the musical theatre and was created in 1988 by York's founding artistic director Janet Hays Walker. David Merrick, Stephen Sondheim, Stephen Schwartz, Harold Prince, Jerry Herman and Cy Coleman are past recipients. Last year's award was given to the songwriting team of John Kander and Fred Ebb.

Mackintosh, who is the producer of the current revival of Oklahoma!, will be feted by an array of Broadway and Off-Broadway performers, including Liz Callaway — a recent Drama Desk Award nominee for her performance in this season's The Spitfire Grill — who spent several years belting out "Memory" in Mackintosh's award-winning Cats. Other performers will be announced shortly.

The producer of such international hits as Cats, The Phantom of the Opera, Les Misérables and Miss Saigon, Mackintosh was knighted in the 1996 New Year's Honours for his services to the British theatre. The 56-year-old U.K. native owns seven West End theatres including The Prince Edward, Prince of Wales, Gielgud, Queens, Wyndhams, Albery and the Strand. More details and ticket information to be announced soon on Playbill On Line.
