The 68-year-old host of "A Prairie Home Companion" spoke for the first time about his retirement plans to the AARP Bulletin.
"I am planning to retire in the spring of 2013, but first I have to find my replacement. I'm pushing forward and also I'm in denial. It's an interesting time of life," Keillor told the magazine.
"I sure don't want to make a fool of myself and be singing romantic duets with 25-year-old women when I'm 75. But on the other hand, it's so much fun. And in radio, the lighting is right."
