Country music star Waylon Jennings was “doing just fine” after 3 1/2 hours of triple bypass heart surgery, a Nashville, Tenn. hospital spokeswoman said. “There was no evidence of a heart attack,” Bridget Dolan, the Baptist Hospital spokeswoman, added after the operation. The 51-year-old singer was hospitalized Sunday morning after having chest pains while traveling to a concert in Bristol, Tenn. Jennings’ wife, singer Jessie Colter, and son were with him at the hospital, and the entertainer was in good spirits before surgery, Dolan said.
