Garrison Keillor reports he is "feeling good" after surgery Thursday at Mayo Clinic in Rochester.

"The IV went in and night fell and a couple hours later I woke in Recovery, no fuss, with a very pleasant nurse who gave me some ice to chew on and we chatted like old pals and at noon I got wheeled up to my room for a lovely lunch of vegetable broth, coffee, cranberry juice, and orange Jell-O," he posted on Facebook.

The Minnesota writer and "Prairie Home Companion" host has not disclosed the precise nature of the procedure, but earlier this month when he announced he was canceling Saturday's "PHC," he wrote: "If you've noticed my upstairs bathroom light go on at 10 p.m., 10:10, 10:25, 10:40, etc., you know all you need to know."

No word on when he'll leave the hospital. In his Facebook post he joked, "The Scot in me says, 'you will pay for this someday' and maybe so but meanwhile I am having a very good day, made all the better by a funny phone call from my daughter. Who reminded me that long ago in this hospital coming out of a tonsillectomy she stuck her tongue out at me. Despite anesthesia she remembered that I was the Judas who took her into the OR."

Keillor, 72, is scheduled to return to the Fitzgerald Theater stage Oct. 4 for a "Prairie Home" show featuring bluegrassers the Gibson Brothers and local singer/songwriter Ellis.

But don't be surprised if he makes an appearance this weekend at the History Theater in St. Paul, where his playwriting debut, "Radio Man," opens Saturday night.

(In the photo at right, Keillor clowned with actor Pearce Bunting, who plays his alter ego in "Radio Man," during a rehearsal earlier this month. The play has a preview staging Friday night.)

P.S. After this was posted, a friend shared a letter to the Anoka County Union that Keillor wrote two weeks ago after an outing to his old high school. It's quite sweet:

To the Editor:

Last Friday, I drove up to Anoka for the Anoka-Coon Rapids football game and sat in the bleachers about 10 feet below the pressbox where, as a 14-year-old kid, I sat and wrote up the games for the Anoka Herald.

Goodrich Field looks so much the same as it did back then and off to my right was a student cheering section, about 300 strong, distinguished by wearing odds and ends of white, white shirts, headbands, caps, one boy in a white off-the-shoulder toga, tossing white streamers, setting off white smoke bombs – a solid block of high spirited goofiness and tumult and swaying and dancing in the stands – in their whiteness, the opposite of goth, more like moths fluttering at a porch light, and so utterly different from the self-conscious solemnity of the Fifties teenager. I know alcohol and this was not alcohol: this was joy and humor and hormones. The band got to play the Fight Song a couple times and I joined the throng in the end zone and the game ended, Anoka up 14-6, and the kids in white bolted for the field and a huge mash-up of bodies at midfield, arms in the air, chanting the Fight Song, and then headed for the exits, a river of youth with a happy alumnus of 72 in their midst. If these folks represent what it's like to be young now, I am all in favor of it.

A joyful September night in my old town and the downtown cafes crowded and my old stately junior high standing big and proud on Second Avenue, where my dad graduated in 1931. Go, Tornadoes.

Garrison Keillor, St. Paul
