My grandaddy was a miner but he finally saw the light. He didn't have much just a beat-up truck and a dream about a better life. Grandmama cried when she waved goodbye never heard such a lonesome sound. Pretty soon the dirt road turned into blacktop Detroit City bound. Down that hillbilly highway. That hillbilly highway. Hillbilly highway. Goes on and on. He worked and saved his money so that one day he might send. My old man off to college to use his brains and not his hands. Grandmama cried when she waved goodbye never heard such a lonesome sound. But daddy had himself a good job in Houston one more rollin' down. Down that hillbilly highway. That hillbilly highway. Hillbilly highway. Goes on and on. Grandaddy rolled over in his grave the day that I quit school. I just sat around the house playin' my guitar Daddy said I was a fool. My mama cried when I said goodbye I never heard such a lonesome sound. Now I'm standin' on this highway and if you're going my way. You know where I'm bound
