Hank Williams Jr. has left Oklahoma fans disappointed, though he’s planning on making it up to them. The legend posted on Instagram he had to postpone his shows Friday and Saturday as he’s feeling under the weather. His shows in Tulsa and Thackerville would be postponed, with Hank rescheduling them for September 19th and 20th. “We regret any inconvenience this may cause and truly appreciate your understanding and support,” the post read. “We can’t wait to be back on stage with you soon.”
