One of the staples in country music is nostagia. "The Grand Ole Opry" has been playing for almost 90 years and it shows no signs of disappearing.
There have been so many good singers that have sung country, Hank Williams, Hank Snow, Johnny Horton, Mary Robbins, Patsy Cline, Conway Twitty, Eddy Arnold, Jim Reeves, Johnny Cash etc. etc. Most died relatively young, but others passed away at a ripe old age.
I remember those entertainers not because they were country singers or part of the Grand Ole Opry, but because they were artists and songwriters that told stories that related to the human condition.
George Jones can communicate it much better than I can communicate it in a blog entry.
