This week on A Prairie Home Companion, we're coming to you live from the Fitzgerald Theater in downtown St. Paul to journey through the world of radio with broadcast news veteran Harry Smith, of CBS fame. We'll welcome back some old friends, too: the boot-stompin', fiddle-pluckin', heart-breakin' Old Crow Medicine Show, honky-tonk heroes Robin & Linda Williams and Their Fine Group , as well as the Royal Academy of Actors: Tim Russell, Sue Scott, sound effects man Tom Keith, and The Guy's All-Star Shoe Band. Plus, Guy Noir and the late-breaking news from Lake Wobegon. Don't touch that dial!
