George Jones has died at the age of 81. The legendary country singer was admitted to the hospital with a fever and irregular blood pressure yesterday before passing away this morning. Jones had a series of hits during the 1960s and 70s, including “If Drinkin’ Don’t Kill Me (Her Memory Will),” “Window Up Above,” “She Thinks I Still Care,” “Good Year for the Roses” and “The Race Is On.” His 1980 single “He Stopped Loving Her Today” charted at No. 1 and was voted the greatest country single of all time by a selection of fans and music industry insiders. The song also got him a Grammy for Best Male Country Vocal Performance.

Jones struggled with substance abuse (primarily alcohol and cocaine) issues throughout his life, but was able to clean up after he was seriously injured after crashing into a bridge while driving drunk in 1999. The singer was in the middle of a tour when he was hospitalized. He was scheduled to perform with Kenny Rogers, Randy Travis, Garth Brooks and Kid Rock when his tour came to a close in Nashville in November.
