The Curran Theatre is still thriving under the aegis of Carole Shorenstein Hays and the Messrs. Nederlander who, since 1978, have presented a wide spectrum of plays and musicals.Through their "Best of Broadway" series, San Francisco audiences have enjoyed everything from Shenandoah to Fences to Les Miserables. Not merely a memory or a monument, the Curran is still what it was intended to be - part of the excitement of San Francisco.
