MINNEAPOLIS (AP) — “Prairie Home Companion” radio show host Garrison Keillor says he has suffered a brain seizure but his show apparently will go on.

The 73-year-old Keillor posted on Facebook Thursday that he had what he called a “whirlwind weekend,” doing two shows back-to-back at Wolf Trap National Park for the Performing Arts in Virginia and suffering a “nocturnal brain seizure.”

He flew to Mayo Clinic where he underwent an MRI, which showed what he called a “black hole” where a previous stroke had struck near his brain’s language center. He said a doctor put him on medicine to stop convulsions that makes him feel lethargic but he intends to fight.

His publicist, David O’Neill, said Keillor still planned to fly to Atlanta on Thursday to host a show on Saturday.
