We scanned the Dallas Opera's cast list for its production of Cinderella, trying to find out which of opera's greatest stars would portray the helpful mice who make a ball gown for Cinderella. That "Cinderelly, Cinderelly" song is our favorite, second only to the fairy godmother's big moment in "Bibbidi-Bobbidi-Boo." Only there were no mice listed. No fairy godmother, either. Turns out Gioachino Rossini's Cinderella doesn't have the magical mice and kindly old lady so beloved in Walt Disney's version. But wait, there's more. The slipper is replaced by a bracelet, reflecting the modesty of the 1800s, when Rossini wrote his opera. This old-school version of Cinderella will be performed by Vivica Genaux and Margaret Lattimore (who share the lead role) at 7:30 p.m. December 10, 2 p.m. December 12 and 7:30 p.m. December 15 and December 18 at the Music Hall at Fair Park. Tickets are $19 to $265. Call 214-443-1000.
