In an interview with AARP, Garrison Keillor said he plans to retire in "the spring of 2013," so this may be your last chance to see the legendary author, storyteller, humorist, and creator of the weekly radio show "A Prairie Home Companion." The show began in 1974 as a live variety show on Minnesota Public Radio. In the 1980s "A Prairie Home Companion" became a pop culture phenomenon, with millions of Americans listening to Keillor's folksy tales of life in the fictional Midwestern town of Lake Wobegon, where (in Keillor's words) "the women are strong, the men are good looking, and all of the children are above average." His radio show inspired a 2006 movie, "A Prairie Home Companion," written by and starring Keillor, Meryl Streep, and Lindsay Lohan, and directed by Robert Altman. It was Altman's last film; he died later that year. His signature sign-off on his show "The Writer's Almanac" is "Be well, do good work, and keep in touch."
