My favorite TDN song is "Never Been to Spain." Waylon Jennings covered it on his 1976 live album, but I am going to link his version from January 2000 - his final concert appearance before passing away about a month later. He played the entire concert sitting down - and got some boos for it - but the audience didn't know that he was about to have his foot amputated due to complications from diabetes, and that he would be dead in just a few weeks.
