Garrison Keillor did “A Prairie Home Companion” for forty years, wrote fiction and comedy, invented a town called Lake Wobegon where all the children are above average, even though he himself grew up evangelical in a small separatist flock where all the children expected the imminent end of the world. He’s busy in retirement, having written a memoir and a book of limericks and is at work on a musical and a Lake Wobegon screenplay, and he continues to do “The Writers Almanac” sent out daily to Internet subscribers (free).

After fifty years in radio, Garrison Keillor is launching out on a solo stand-up career, his longtime dream, but due to his evangelical upbringing he has a solemn face and his literary history has limited his emotional range, so he has turned to his niece Erica Rhodes, a successful young stand-up, for instruction. She shows him her style and he does humorous verse, limericks, songs for her, and she tries to help him smile and use the space. A meeting of two generations.
