Not many stage shows can take you back in time—much less twice. Such is the case with the touring musical Dirty Dancing: The Classic Story on Stage, which comes to the Citi Emerson Colonial Theatre April 28–May 10. Not only is the production based on the hit 1987 Patrick Swayze-Jennifer Grey film, but it also takes audiences back to the not-so-innocent days of 1963. Re-live one of the quintessential movies of its era as the vacationing Frances “Baby” Houseman falls for bad-boy dance instructor Johnny Castle, all to the beat of such favorite songs as “Do You Love Me?,” “Hungry Eyes” and the Academy Award-winning “(I’ve Had) The Time of My Life.”
