Rudetsky will offer 7 and 9 PM shows of Rhapsody at the Ars Nova Theater on Sept. 28. Rudetsky's self-penned show, in which he rhapsodizes about the talents of high belters Betty Buckley, Patti LuPone and the late Laurie Beechman, played an extended engagement at the Actors Playhouse in spring-summer 2003.

A mix of comedy and drama, the show features a discussion of the difference between a woman's "head" and "chest" voice. The comedic actor also recalls growing up in North Woodmere, Long Island, where he was praised for his musical gifts but ridiculed for being gay. Rudetsky, however, had the last laugh, working his way to pianist and musical director for several Broadway shows and comedy writer for "The Rosie O'Donnell Show."

The Trevor Project is a group that "constructively raises issues of tolerance and acceptance among today's gay and questioning youth, their parents and their peers, demonstrating that there are positive solutions to the problems they encounter." Visit www.thetrevorproject.org for more information.

Creator and host of Seth's Broadway Chatterbox, Seth Rudetsky has served as a pit pianist and/or conductor for such Broadway shows as 42nd Street, The Full Monty, The Phantom of the Opera, Mamma Mia! and The Producers. He also conceived the idea for the all-star Chess concert to benefit the Actors' Fund of America as well as the two previous benefit concerts, Funny Girl and Dreamgirls. Rudetsky was a member of the comedy writing team for "The Rosie O'Donnell Show" for two years, and his awards include the Duplex's Stars of Tomorrow, the Backstage Bistro and the Funniest Gay Male in New York. He will also musical direct the upcoming Hair benefit concert.

Tickets, priced at $20, are available by calling (212) 868-4444 or by visiting www.smarttix.com. The Ars Nova Theater is located in Manhattan at 511 West 54th Street.
