George Jones is back in the hospital, two weeks after being released following a near-fatal car crash. The country singer was taken to Nashville's Vanderbilt University Medical Center on Tuesday and was listed in fair condition. He has "an irregular heartbeat," said a spokesman for Jones' record company. "They think it could be due to dehydration." Jones, 67, spent two weeks at Vanderbilt after nearly dying March 6 when he crashed his sport utility vehicle into a bridge near his Franklin home. (A half-empty half-pint of vodka was found in the wreckage. A grand jury will consider next month whether Jones will face charges.) He went home March 19.
