Ray Frewen's production of Meredith Willson's quintessential middle-American musical--aided by Gregory Slawko's colorful, period-perfect costumes and James Zager's sassy choreography--captures its exuberance, tartness, and mischief. Gene Weygandt is the lovable Professor Harold Hill, sauntering through River City with a great sense of rhythm and self-assured charm as he rips off the citizens for uniforms and instruments the kids will never play (though someone should slip him a Red Bull before high-powered numbers like "Trouble" and "Seventy-Six Trombones"). Catherine Lord shows warmth and strength (and an occasionally wobbly soprano) as Marian, the librarian whose love trips up Hill. The band plays on, and the ensemble sparkles. Through 5/22: Wed 8 PM, Thu 2 and 8 PM, Fri 8:30 PM, Sat 5:30 and 9 PM, Sun 2:30 and 7 PM. Drury Lane Oakbrook, Roosevelt and Butterfield, Oakbrook Terrace, 630-530-0111. $22-$26; dinner packages available.
