NASHVILLE, Tenn. (AP) — Country superstar Alan Jackson revealed in an interview Tuesday that he has a degenerative nerve condition that affects his balance but he intends to keep performing.

Jackson, 62, said in an interview aired on NBC’s “Today” show that he was diagnosed with Charcot-Marie-Tooth disease a decade ago. He said it was a genetic condition and its effects on his ability to walk have been getting more noticeable.
