Like Stephen Sondheim, downtown darling Ruth Margraff found new inspiration in Aristophanes' comedy The Frogs. Her retelling, a burlesque entitled Red Frogs, will premiere Feb. 28-March at P.S. 122 with Obie winner Jan Leslie Harding in the cast. Elyse Singer directs.

A group of rowdy Coney Island working girls lead Red Frogs in a comic uprising against the queen of all media at the diva's summer home in Nantucket. Margraff's many works include Night Vision (a third to first world vampyre opera), The Cry Pitch Carrolls, Once Upon a Time in Chinese America and The Elektra Fugues.

Harding won her Obie for Mac Wellman's Sincerity Forever. Other credits include Killer Joe, Defying Gravity, The Green Bird and several pieces by Richard Forman. Joining her in the cast are Nina Hellman, Molly Powell and Steven Rattazzi.

Red Frogs' designer teams features Juman Malouf (sets), Kaye Voyce (costumes), Traci Klainer (lighting), Into the Woods' Elaine J. McCarthy (projections) and Laura Brown (sound).

Tickets are $17. P.S. 122 is located at 150 First Avenue. For more information, call (212) 477-5933. — By Christine Ehren
