The always fabulous Sandra Bernhard debuted her latest solo show, “I Love Being Me, Don’t You?”, at NYC’s Town Hall on June 8, and she didn’t have to do it alone: To raucous applause, Bernhard welcomed special guest Liza Minnelli to the stage for a duet of “Class,” Mama Morton and Velma Kelly’s comic lament from Chicago. Both ladies were in fine voice (and coordinated in sequins) during the number and obviously enjoyed each other's company. Click on for a glimpse at a pair of theatrical icons.
