Written by: Entertainment Columnist Jerry Fink Hearing Voices: Impressionist/vocalist/comedian Bethany Owen gave a memorable performance at the Stardust on Friday night, demonstrating her skill of mimicking dozens of celebrities. Owen, based in Los Angeles, tours the country performing at clubs and corporate events. She would be a welcome addition to the Vegas entertainment scene -- Owen has great comedic timing, a fine singing voice and most of her impressions are dead on. Her Sarah Vaughan, Billie Holiday, Lena Horn, Peggy Lee, Fran Drescher and Marilyn Monroe numbers were especially intriguing. Owen shares the stage with dozens of wigs and costumes, which she changes into in front of the audience. Among her funniest numbers is a Martha Stewart version of "Jailhouse Rock," and the voices of the mothers of celebrities such as Jackie Mason and Andy Rooney.
