Every year Noble Fool Theatricals comes up with a scant story line for this Christmas program of songs, dances, and comedy sketches revolving around Gina Oswald, star of an over-the-top holiday special, and her long-suffering Zeitgeist Zingers. This time they’re trying to land a gig in Alaska, but the smooth crooner looking for a partner there is also considering Gina’s older, raunchier sister, Roxy. Patricia Musker–hilarious once again as the ambitious lounge singer with no consciousness of her own excesses–plays both roles, which requires some arguments to take place offstage and a couple of quick costume changes. Ultimately Roxy’s story is left unresolved, but no big deal. The show’s joys, as always, are its holiday medleys, Gina’s quirky supporting singers and staff, and her audaciously festive costumes (designer Kimberly G. Morris is superb at gaudy and glitzy). Through 12/31: Wed 2 and 8 PM, Thu-Fri 8 PM, Sat 4:30 and 9 PM, Sun 2 PM. Wed 12/8, 8 PM only. Upcoming holiday schedule varies; call for information. Pheasant Run Resort & Spa, 4051 E. Main (Rte. 64), Saint Charles, 630-584-6342. $27-$37; dinner-show packages available.
