Hank Sr, Hank Jr, and Hank III, are all great talents, and very different styles from each other. Although Hank III can belt out a moaning blues tune, and sound just like his grandaddy, just be prepared for his last set when on stage, it ain't anything like his dad or his grandads music. I recommend everyone should check out Hank Willimas III if you get a chance.
"If The Devils Got A Daughter"
His redition of "Cocaine Blues"
Or if you prefer "Mary Fu@#$ngJane"
