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, 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 “where all the women are strong, all the men are good-looking, and all the children are above average.” The show is heard by 4 million listeners nationwide on nearly 700 public radio stations each week.
