Country Music Hall of Fame member Merle Haggard is still recuperating at a Macon, Ga., hospital after other ailments were discovered while he was being treated for pneumonia. The 74-year-old singer-songwriter canceled a Jan. 17 tour date in Macon and was immediately admitted to the local hospital after being diagnosed with pneumonia. He checked himself out of the hospital on Friday (Jan. 20) and boarded his tour bus to his home in Redding, Calif., where he planned to receive additional treatment for pneumonia. Realizing he wasn’t well enough to make the 2,600-mile trip, he returned to the Macon hospital where he was also diagnosed with three stomach ulcers, eight polyps in his colon and diverticulitis of the esophagus. Haggard underwent surgery for lung cancer in 2008. He has canceled the remainder of his January tour dates. According to his website, he’s scheduled to return to the road for a Feb. 28 concert in Tucson, Ariz.
