Susan Mosher, who currently plays the Female Authority Figure in the Broadway company of Hairspray, will join recording artist John Boswell in the multimedia musical show, which combines film and live performance. Show time is 9:30 PM April 15. Mosher plays Pepper Cole in Cashino with Boswell as Johnny Niagra. Each show, according to press notes, "opens with one of four different short films (chock full of surprising cameos!) about the lives of two legendary singers and their continuing struggle to become internet entrepreneurs. . . Johnny and Pepper then entertain audiences in person with a high energy, high strung and emotionally charged live set."

Susie Mosher made her stage debut in the West Coast premiere of Godspell. She has been seen Off-Broadway in Suds and Back to Bacharach and David, and her screen credits include "Without a Trace," "Three Sisters," "Snoops," "Veronica's Closet," "The L Word," "A View From the Top," "The Wedding Planner" and "Lost Souls."

The Laurie Beechman Theatre is located in Manhattan at 407 West 42nd Street. There is a $20 cover charge and a $15 food-drink minimum. Call (212) 695-6909 for reservations.
