Cast members of 30 Rock and Saturday Night Live may be out of production due to the WGA strike yet still are bringing the funny via live performances at the New York Upright Citizens Brigade Theatre. According to Playbill.com, the unadvertised one-night-only performances quickly sold out, with all proceeds benefiting the Writers Guild strike fund.

On Saturday, the current SNL cast will present a collection of favorite sketches, and the evening will feature host Michael Cera ( Arrested Development) and musical guest Yo La Tengo. On Monday night, Rock stars Tina Fey, Tracy Morgan, Jane Krakowski and Alec Baldwin will perform an episode from the series. Beep, beep, ribby, ribby!
