On Nov. 7 and 21 and Dec. 5 and 19 Rudetsky will offer his one-man show, Deconstructing: The Good, The Bad and The Headachy. Show time is 9:30 PM.

Rudetsky's show will feature dozens of clips from his private video collection. The performer will show audiences how to "deconstruct." "Learn how to analyze 70's variety shows," reads a press statement, "and question why there was a distinct lack of blinking. You’ll be able to differentiate the best belting in the world versus Bonnie Franklin. Judge classic videos like 'The Brady Bunch Variety Hour,' The Liza/Joel Grey/Ben Vereen Spiritual Medley, and Barbra Streisand forced to sing 'People' down a third and then a fourth as she progressively ages."

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 On the Twentieth Century concert to benefit the Actors' Fund of America as well as the four previous benefit concerts, Hair, Chess, 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 was also the author and star of the recent one man, GLAAD nominated show Rhapsody in Seth.
