Geez man, whats the problem.
Hank Jr. doesn't need to "come-back", he never went away. Besides that, the man made enough money on the origional version of that song alone to last him 3 lifetimes.
I'm certain if you look into it, you'll find Hank Jr. to be one of the more patriotic types you'll find in the entertainment industry.
Animal, Hank Williams Jr. is the son of ..err (lol) Hank Williams, who is considered by most the father of country music (ok, Bob Wills is in there too). Anyway, Hank Jr. established himself in the country music industry and achieved even greater fame (arguable) than did his dad. In his younger days he was pretty much a failure in the music buis, until he cut away from dad's style of music and started his own thing. The name helped allot, but he's done more for himself. And..ya he looks like funked lol (but)...the beard is hideing some serious damage he got from some accident he had way back when. If memory serves me correctly, he ran a hang-glider into a cliff or was rock-climbing or some crap like that and suffered pretty serious injuries through a fall.
Anyhoo, his music (IF you like country) is good stuff. ...pretty much couldn't go to a party in the 80's without a few of his poppin up lol (or watch Monday Night Football well into the 90's)
