(MIDNIGHT MOVIE) Here for one night only is your chance to belt out “When Doves Cry” or “I Would Die 4 U” or even “Darling Nikki” (if you ain’t yella) with 400 of your closest strangers. The event: A Purple Rain sing-along, with lyrics to the forever-brilliant songs projected right along with the dated-by-unapologetic-misogyny film. Your host: San Francisco drag queen Peaches Christ. The result: surefire lunacy. Dig out your purple and lace–Prince and Apollonia arrive at midnight! (Egyptian Theatre, 805 E Pine St, 781-5755. Midnight, $9.)
