Sorry to hear this. He was actually the last big name concert I went to (way back in ‘98). Mama Tried one of my all time favorites.
He was supposed to come up my way back in about 1995 or 1996, but had to cancel due to health issues. RIP Merle, loved your music (including “Okie from Muskogee”) when my peers in university were spaced out on Zeppelin or grunge or alternative.
