Entitled Seth's Broadway 101: A Master Class in Belting, Divas, and Hostile Opinions, the evening is being held at New World Stages. Show time is 7:30 PM. Rudetsky will be joined by a host of Broadway favorites for the benefit performance, including Laura Benanti, Charles Busch, Kristin Chenoweth, Raul Esparza, Norm Lewis, Andrea McArdle, Pamela Myers and Julia Murney. "Using a full orchestra," read press notes, "audio/visual aids and talents of Broadway guest stars, Seth will show the audience what is brilliant about Broadway, how it works and why it sometimes can be a splitting headache!" Peter Flynn directs.

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 recent all-star The Best Little Whorehouse in Texas concert to benefit the Actors' Fund of America as well as the five previous benefit concerts, Hair, Chess, Funny Girl, On the Twentieth Century 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 was also the author and star of the recent one man, GLAAD nominated show Rhapsody in Seth, and his new tome — "The Q Guide to Broadway" — was published by Alyson Books. Rudetsky has been seen on "Law & Order" and "All My Children."
