The venue for this interactive show a la Tony 'n' Tina's Wedding is a dance club, and the concept is that various character types from teen angst movies are attending Wanaget High's 1989 prom. But the show's jock, cheerleader, geek, exchange student, and outsiders (named Fender and Dickie and costumed just like John Hughes's Bender and Duckie) are never fleshed out. And though familiar stories of high school conflict are flimsily reenacted on occasion, most of the show loses the battle with the club's blaring music and bar chatter. But if dancing to Rick Springfield and Huey Lewis while drinking appeals to you, the show's failings won't matter--it's just background noise, an excuse for a moonwalk down memory lane. Through 12/31: Thu-Sat 7:30 PM. RadioStar, 901 W. Weed, 312-664-7766. $39-$69 (includes postshow "video dance club"; various packages available).
