This week on A Prairie Home Companion, we're back at Town Hall with this season's talent contest: The Great American Duet Sing-Off. The six pairs of finalists will be singing their hearts out for your vote, the grand prize, a silver water tower trophy, and the title of Wobegon Idol. Also with us, the Royal Academy of Radio Actors; Tim Russell, Sue Scott, Erica Rhodes, and Fred Newman, The Guy's All-Star Shoe Band, and The News from Lake Wobegon.
