This week on A Prairie Home Companion with Garrison Keillor, a summer rebroadcast of a wintry show originally from January 2012 at The Fitzgerald Theater. Brad Paisley plays "This is Country Music," Cantus perform "There's a Meetin' Here," and Andra Suchy and Garrison sing "Log Cabin Home in the Sky." In Lake Wobegon, the town's ice fishermen deal with an unexpected lack of ice.
