Due to another commitment, comedienne-actress Rivers has bowed out of the Aug. 4 evening, which will now feature Tony Award winner Graff and director-actor Lonny Price. This is the first of several Monday evenings of the acclaimed Gurney work being presented at the Duplex Cabaret Theatre in New York's West Village.

Graff and Price will be followed by pairings of Charles Busch and Jim Dale (Aug. 11), Alison Fraser and Stephen Bogardus (Aug. 18), Daisy Eagan and Matt Bogart (Aug. 25), Phil Geoffrey Bond and Kristy Cates (Sept. 1), Seth Rudetsky and Leslie Kritzer (Sept. 8), Tonya Pinkins and Jerry Dixon (Sept. 15) and Andrew Lippa (Sept. 22).

Randy Graff recently starred in the Williamstown Theatre Festival's mounting of The Threepenny Opera. She received a Tony Award for her performance in Cy Coleman's City of Angels, and her other Broadway credits include A Class Act, High Society, Moon Over Buffalo, Laughter on the 23rd Floor, Falsettos and Les Misérables as well as the City Center Encores! production of Do Re Mi. Off-Broadway she was seen in Hotel Suite, A...My Name Is Alice, Coming Attractions and Pins and Needles. Graff's screen credits include "Keys to Tulsa," "Moon Over Broadway," "Mad About You" and "Law & Order."
