CHICAGO (AP) — Blues guitarist B.B. King has canceled the remaining eight performances of his current tour after being diagnosed with dehydration and exhaustion.

King’s official website says he fell ill Friday evening during a performance at the House of Blues in Chicago and was evaluated by a doctor.

The end of his tour was to include stops next week at his own B.B. King Blues Club and Grill in New York.

The Rock and Roll Hall of Famer is 89 and has released over 50 albums.

No further updates on his condition were provided.

Earlier this year, King issued a public apology to fans after an erratic performance in St. Louis led to audience catcalls and early departures. His publicists called it “a bad night for one of America’s living blues legends.”
