Lake Wobegon, Minn., will materialize at Loyola Marymount University during the final broadcast of Garrison Keillor’s “A Prairie Home Companion” over KUSC-FM (91.5) on June 13. “Night Court’s” Harry Anderson will emcee a “Prairie Home Social,” bidding adieu to Keillor, who is quitting the long-running Saturday-night radio variety show in order to move to Denmark and write full-time. Keillor will host his final show from Minnesota and will not be on hand for the re-creation of Lake Wobegon at the Westchester campus, but KUSC officials plan to set up a life-size cutout of the humorist next to the Olaf Trygvasson High School Gym (Loyola’s Gerston Pavilion) so that fans can have their picture taken with him.
