Following a concert cancellation due to an undisclosed but serious medical issue, John Anderson is doing well and expected to recover fully. A Facebook post to the artist's official page shared an update on his health on Tuesday (Aug. 8).

"We would like to thank everyone for all the prayer and well wishes," the Facebook statement reads. "John is doing great and on the road to full recovery. He will be back on the road in no time!"

On Aug. 1, organizers of a festival in Alabama revealed that Anderson needed to cancel his headlining set, scheduled for Saturday (Aug. 5), due to “unforeseen and serious medical issues” that required Anderson to "remain, for the time being, under the direct care and supervision of a Nashville-area doctor.” Anderson himself has yet to comment on the details of his illness, but a representative tells Country Rebel that the singer-songwriter will remain off the road through Aug. 12.

Anderson, a Nashville Songwriters Hall of Fame inductee, is known for hits such as “Black Sheep,” “Money in the Bank” and more; he’s charted more than 40 singles since debuting in country music in the late 1970s and has five No. 1 hits. Anderson’s most recent album, Goldmine, was released in 2015; it was his first album in nine years, a response to demand from his dedicated fans.

“We did have a record, actually a couple records, but they never got released, so therefore, our fans have been wondering, ‘Are you all going to make any more music?’ or ‘Do you still sing?’” Anderson told The Boot when Goldmine was released. “This particular record, after those kind of dismal attempts of our last few, I wanted to try and be sure we could at least be set up where the fans would know about it when we did make a record.”
