Have to disagree with the OP. While "He Stopped Loving Her Today" is one of the greats, it isn't the greatest. IMNSHO that would belong to Willie Nelson's "My Heros Have Always Been Cowboys". Following in second place would be his song "Mamas Don't Let Your Babies Grow Up To Be Cowboys".
"Serious sport has nothing to do with fair play. It is bound up with hatred, jealousy, boastfulness, and disregard of all the rules."
