by Brian MansfieldThe Kentucky HeadHunters aren't a remarkable country mutation, just a top-notch Southern rock band with a sense of humor. "The Ballad of Davy Crockett" is the kind of clever novelty that won't work twice; "Big Mexican Dinner" is a novelty that doesn't even work the first time. Once again, the country and bluegrass covers -- "Only Daddy That'll Walk the Line," "With Body and Soul" -- are the highlights, and most of the originals (the Beatlesque shuffle "Always Makin' Love" aside) are offbeat, adequate filler.
