Although not a fan of the mostly-80s-style rock music that predominates “Rock of Ages,” the newest Georgetown Palace Theater production opening tonight, I have to admit the acting, and the action in this play are excellent! The lighting work by Faith Castaneda, as always, is wonderful. As director Ron Watson told the dress rehearsal audience last night, this is not a show to bring your small kids. But hey, it’s a good way to spend two hours’ time in gorgeous Art Deco theater on the Georgetown square. The play runs weekends through August 6 on the Springer Memorial Stage.
