Chicago blues singer Katherine Davis, with cowriter-director Tom Arvetis, tells the story of her life in this hour-long family-oriented show--well, the part when she was growing up in Cabrini-Green in the early 60s. A self-described "short, fat colored girl with no neck," she surmounts her self-doubt to enter and win a talent contest. But much more powerful than the show's inspirational message is its live music, ranging from doo-wop to gospel to blues. Accompanied by a five-piece band, the whole ensemble sings, but the standouts are Davis and Lakesha Walker, who plays Davis as a child. Plentiful opportunities for singing and dancing along should carry the kids, and adults can time trip. Through 2/25: Tue-Thu 10:30 AM, Sat 2 PM, Fri 2/17, 10:30 AM, Northwestern University Settlement House, Vittum Theater, 1012 N. Noble (third floor), 773-342-4141, $10-$15. Seating limited at weekday shows; call for reservations.
