Maureen Moore will sub for an ailing Christine Ebersole for the Feb. 27-28 performances of Broadway's Grey Gardens at the Walter Kerr Theatre.

An under-the-weather Ebersole missed the Sunday, Feb. 25 matinee of the musical in which she plays two roles — and sings of the malaise of being stuck in a summer resort by the sea in the dead of winter.

The Tony Award-winning Ebersole "is expected to be fully recovered to return to the show this coming Thursday," a spokesman told Playbill.com Feb. 27.

Maureen Moore, the stalwart standby for Broadway's recent Gypsy, Sunset Boulevard, Cabaret and Song & Dance, provides backup for Christine Ebersole's dual roles. The actress plays Edith Bouvier Beale in 1941 (Act One) and her middle-aged daughter, Edie, in 1973 (Act Two). Ebersole standby Moore was the first replacement Fantine (after Randy Graff) in Les Miserables on Broadway. She made her Broadway debut as June in the 1974 Broadway revival of Gypsy. Years later, she would go on to perform the starring role on Broadway, playing Mama Rose (as standby for Bernadette Peters) in the 2003 revival. Her Broadway credits also include Sunset Boulevard (Norma Desmond), the 1998 revival of Cabaret (Fraulein Schneider), Jerome Robbins' Broadway (Claire), Song & Dance (Emma), Amadeus (Constanze), Falsettos (Cordelia), Big River, I Love My Wife (Cleo) and last season's revival of The Threepenny Opera (Walter). She was also the crisp Charlotte in A Little Night Music for New York City Opera, a staging that was aired on PBS.
