Garrison Keillor

For millions of Americans in love with a little fictional corner of Minnesota, Saturday night is Prairie Home Companion night, and Garrison Keillor is the man who keeps the lamplight burning.

An old-fashioned master of storytelling and the radio review, who plucks at mystic chords of memory until Powdermilk Biscuits and the Chatterbox Cafe pop out. For decades now, he's been at it — on the air, in print, and lately on the big screen. Some call him the new Mark Twain. He's out with a new book called "Pontoon".
