Slinky local ecdysiast Lady Jack makes striptease smart, conveying intelligence and wit with every shoulder roll. She's headlining "Bally Hoo," a 1930s-style supper club and floor show in the technically new but spiritually old-timey nightlife venue Untitled. With its live band, dancers and vaudevillians, this event gives Recession-era Chicagoans the chance to hang out in a Depression-era musical.
