Carly Berg in The Wizard of OzWhile traveling to Thursday's presentation of The Wizard of Oz, which features much-loved songs by Harold Arlen and E.Y. Harburg, I pondered whether the Clinton Area Showboat Theatre's production would stick closely to the familiar images and characterizations from the equally loved 1939 film version. (As I prefer to see local theatre companies presenting unique versions of theatrical pieces, I hoped the Showboat would avoid copycat staging.) But once I settled into my seat, it took just a perusal of the program to know this wasn't going to be my grandfather's Oz, and a sense of excitement blossomed as I eagerly awaited the metaphorical curtain's opening.
