Before it became a midnight movie mainstay, Richard O’Brien’s The Rocky Horror Picture Show was titillating London and Broadway theater audiences in the flesh as The Rocky Horror Show. Ludicrous Theatre allows audiences to get up close and personal with this quirky 1970s musical that blends 1950s-style rock and roll numbers with a sexually expansive plot twist on monster movies. Ludicrous Theatre’s The Rocky Horror Show continues through Saturday, Sept. 17, at BoHo Theatre at The Heartland Studio, 7016 N. Glenwood. Show times are at 8 p.m. Thursdays through Saturdays and 2 p.m. Saturdays and Sundays, plus a midnight show on Sept. 9. Tickets are $20-$25.
