W.C. Fields was famously quoted as saying, “Never work with children or animals,” probably because they're scene-stealing and completely unpredictable. And they certainly were, in the best way, when Thursday's opening-night performance of composer Lionel Bart's Oliver! played to a sold-out crowd at the Clinton Area Showboat Theatre. At the show's start, dozens of exceptionally talented children, playing half-starved orphans, stormed the stage with empty bowls in their hands singing “Food, Glorious Food,” and this classic tale of struggle and hardship was immediately delivered with skilled, scene-stealing, completely unpredictable song-and-dance performances.
