Rogers & Hammerstein'sCinderella is a beloved family favorite, although the 2013 Broadway revival updated the show slightly. In this version, Cinderella makes her handsome Prince aware of his kingdom's horrible oppression of its most vulnerable subjects, which stems from the cruelty of the Prince's chief minister. What's more, Cinderella's stepsister Gabrielle is in love with the crusading Jean-Michel, who's actively fighting the minister's legislation. The Muny presents this new Cinderella at 8:15 p.m. Monday through Tuesday (July 8 to 16) at the Muny in Forest Park (www.muny.org). Tickets are $15 to $105.
