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.
