He only had one huge hit, but had a number of other smaller hits in the Country Music world. So far as I know, they all came off the same album. The one Achy Breaky Heart was on. It was actually a pretty good album & the whole thing was considered a hit album. That was back when singers still depended on "albums" rather than single I-Tunes, or whatever, hits.
Then he had that Doc TV show. I remember it, but had no idea it was on for that long. Then he was on the Disney Hannah Montana TV show playing Miley's character's dad (big stretch, huh?). That was on for a number of years until she turned into whatever the heck she is now. I don't care to give a description as to what that is.
Somehow he has managed to turn his initial hit(s) into a career & stay somewhat in the public eye. You have to give the guy credit for that.
