This week on A Prairie Home Companion, a show for Lutherans and the people who love them. Guy Noir helps out a Sunday School teacher in a bind, Dan Newton and The Guy's All-Star Shoe Band play the "Lutheran Polka," and VocalEssence encourages good works. Plus, a message from Lutherans Online (LOL) and what constitutes a Lutheran summer vacation, or not, in Lake Wobegon. This week's show is brought to you by Lutheran Tours: Designing vacations that make you glad to get back home.
