Who knew that something as benign as bingo could be a cutthroat, super-competitive soap opera, complete with callers enjoying something extra for announcing the right bingo balls, zany rituals performed over cards, rice-cereal-treat bribes, and WWE-style heels and heroes? It just goes to show that the competitiveness of the human experience filters even into the most unlikely and folksy slices of Americana, as demonstrated in Bingo! The Winning Musical, the kooky musical offering at Moline's Playcrafters Barn Theatre.
