Story highlights This is his second seizure within the last year

Keillor has five upcoming live shows that he intends to make "terrific"

The American icon is expected to retire after 40 years in radio

(CNN) Radio legend Garrison Keillor says he's feeling "fortunate" after the Prairie Home Companion host suffered a seizure over Memorial Day weekend.

According to a message posted on his Facebook page, he hosted two back-to-back shows at the Wolf Trap National Park for the Performing Arts in Vienna, Virginia, on Friday, May 27, after suffering from a medical emergency.

Keillor said after the shows he "flew to Mayo to get checked out and saw an MRI image of my skull with a black hole where a previous stroke struck close to the language center of the brain, so I came away feeling vastly fortunate."

When he was discharged from the Mayo Clinic, Keillor said he went home to St. Paul, Minnesota, and then boarded a flight to Atlanta to host a show at the Fox Theater, according to David O'Neill, Prairie Home Companion publicist.
