The opera world was shocked when Aristotle Onassis dumped Maria Callas for Jackie Kennedy–but not half as shocked as Callas herself might be to learn of her illegitimate daughter “Dagmar Onassis,” who’s existed for a decade now in the person of actor-dancer-singer John Kelly. Kelly, who blends Bizet and Bellini with Monteverdi and Mahler (not to metion the occasional Kurt Weill tune or black spiritual), started out lip-synching Callas’s Carmen in gay bars and performance spaces in New York’s East and West Villages. A chameleonic caricaturist, he’s long since stopped lip-synching; Dagmar (an alto) is now noted for her vocal beauty and musical precision as well as her high-style emotionalizm. Having perfomred small- and large-scale works around the UlS., Europe, and South American since the early 1980s, the Obie Award-winning Kelly is finally making his Chicago debut this weekend as guest star of Milly’s Orchid Show, Brigid Murphy’s oddball avant-garde variety extravaganza. Besides Dagmar, Kelly will offer his eerily accurate impersonation of Joni Mitchell; the program also includes monologuist David Sedaris and Murphy herslef, in the role of hostess Milly May Smithy, modeling a line of nighties and leading the audience in a session of Milly-cize. Park West, May 2 (322 W. Armitage, 929-5959). Saturday, 8:30 PM (doors open 7:30 PM). $10.
