Molly Ringwald's biggest claim to fame comes from her trilogy of 1980s teen films, Sixteen Candles, The Breakfast Club and Pretty in Pink. But the belle of the Brat Pack has musical experience, too, having played Sally Bowles in the Broadway revival of Cabaret and, at age 6, recording a jazz album with her father's band. She again shows off her musical chops as the optimistic but downtrodden dance hall hostess Charity Hope Valentine in SWEET CHARITY, playing tonight Sat., MARCH 24, at the Fox Theatre. Through March 25. $19-$56. Sat., 2 and 8 p.m.; Sun., 1 and 6:30 p.m. 660 Peachtree St. 404-817-8700. www.foxtheatre.org.
