This week it's a live broadcast from the Minnesota State Fair. This annual Mecca for Norwegian Bachelor Farmers hosts a show from the historic State Fair Grandstand. We welcome folk star Shawn Colvin, Minnesota-based a capella quartet Tonic Sol-Fa, and the Marching Wolfpack of Cottage Grove, Minnesota, as guests, as well as the regular crew: The Royal Academy of Radio Acting, Tim Russell and Sue Scott; sound effects from Tom Keith; and Rich Dworsky and the Guy's All-Star Shoe Band, joined this week by fiddler John Neiman.
