Rachelle Walljasper, Brad Hauskins, Chad Willow, Tristan Layne Tapscott, Andrew Crowe, and Steve Lasiter in Southern CrossroadsA sign in front of the Circa '21 Dinner Playhouse includes a description of the theatre's current show, Southern Crossroads, as "an inspiring and hilarious story about one musical group's struggle against impossible odds, as they find new hope through music." That line fits Circa '21's production to a T, as the tone of director Curt Wollan's offering is clearly joyful, despite the sense of desperation in its setting. With the appropriate exceptions of those playing villains, Wollan's cast does not play up any silliness written into their comedic lines. Instead, they choose to play them straight, and in doing so, add to the musical's air of Great Depression uncertainty.
