It always scares me when big artists start cancelling shows.

I didn't know he wasn't doing well enough that he had to cancel.

Country music star George Jones has been forced to postpone upcoming shows as he continues to recover from upper respiratory infection.

The 80-year-old singer, best known for hits such as "White Lightning" and "He Stopped Loving Her Today," postponed shows in Minnesota and South Dakota on April 20 and 21 after doctors advised the singer to remain resting for another week. The shows will be rescheduled for a future date.
