Country legend Merle Haggard is returning home to California after canceling a show in Ft. Worth, Texas this weekend. The 74-year-old singer was briefly hospitalized after feeling ill before a scheduled show at Billy Bob's in Ft. Worth. Haggard spokeswoman Tressa Redburn tells the Associated Press that he'll be checked out by his doctors upon returning home.

Redburn shared that Haggard went into the hospital on Saturday for some tests, and left early Sunday morning. She didn't detail what symptoms or illness he might be suffering from, however. Haggard had surgery for lung cancer in 2008, but hasn't shown signs of poor health since. In fact, he raved about his recent energy levels. In a statement to announce his upcoming new album, the singer said, “I’m swinging back in full throttle right now. Music keeps me alive. It makes me breathe better. It’s funny, but I feel better when I come off a tour than when I start out.”

The album -- Haggard's 77th studio project -- is called 'Working in Tennessee' and will be available on October 4. It features nine songs written or co-written by the 'Okie from Muskogee' singer. The remaining two are his renditions of the Johnny Cash hits 'Cocaine Blues' and 'Jackson.' His wife Theresa and daughter Janessa helped him write many of the songs on the project.
