Hank Williams my Dad use to love, I remember he had a Hank Williams cassette in his car, and EVERY time and i mean every time I was driving with him, that cassette would be playing. I must have heard
Move It On Over, and Mind Your Own Business a thousand times before i was 17. His voice use to annoy the hell out of me, but I later appreciated him.

Merle, i like, took a while but i like him quite a bit now
