The 82-year-old singer, considered one of the genre's greatest singers, is in the midst of a year-long goodbye tour that wraps up in November in Nashville. He has occasionally canceled or postponed shows in the last year because of health issues.
The 1992 Country Music Hall of Fame inductee recently announced he was bringing the curtain down on his recording career. After making records since the 1950s, (His first Billboard top ten was 1955's "Why Baby Why") and placing more singles on the country chart than any other artist, he told Billboard earlier this year that he was starting work on his final release, with the help of Dolly Parton.
His Grand Tour, which started in February, is to be his last. Jones has missed shows through illness as recently as last November.
