Nashville playwright Myra Anderson Stephens has a fondness for parody, and her new holiday opus treads that familiar territory with a lampoon of Southern ways — including dental issues and death — all wrapped up with humor and a loving Christmas spirit. Stephens directs as well, and her cast features a mix of respected Music City players and some newer faces, including Joy Tilley Perryman, Adrienne Hite, Betty Haynes Davis, Bakari King, Matt Coram, C.F. Railing, Melissa Williams, Adele Akin and Tracy Harp. There’s also a different celebrity guest actor in each of the six performances, and 15 percent of every night’s proceeds will be donated to that Nashville notable’s favorite charity. Among the celebs scheduled to appear are Metro Councilman Jason Holleman, BroadwayWorld.com reviewer Jeffrey Ellis, NPR’s Bradley George and the Rev. Rick Britton of St. Ann’s Episcopal Church.
