Garrison Keillor, creator and longtime host of the popular “A Prairie Home Companion” radio show, says he means it this time: He’s retiring. In an interview Monday with The Associated Press, Keillor said he plans to step down as host after next season — following four decades of entertaining listeners with his baritone voice and folksy comedy sketches about Lake Wobegon, his mythical Minnesota hometown. The show is heard by 4 million listeners nationwide on nearly 700 public radio stations each week. Keillor also takes summer bus tours for live shows, and his 30-city “America the Beautiful” cross-country tour, billed as his farewell tour, starts next week.
