This week on A Prairie Home Companion, a combination of shows we've done from the campus of St. Olaf College in Northfield with The St. Olaf Choir singing "Norge, mitt Norge," the Orchestra playing Shostakovich, Heather Masse singing the "Lutheran Song," and Guy Noir on the trail of a missing student. Plus, Philip Brunelle outlines the history of choir pianists at St. Olaf and the story of Clarence Bunsen and his friend Cliff and how they met at St. Olaf.
