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  
 
You never heard such a lonesome sound  
 
Pretty soon the dirt road turned into blacktop, Detroit City bound  
A 
Down that hillbilly highway  
 
On Ttat hillbilly highway  
                     D7 
That old   Hillbilly highway  
            A 
Goes on and on  
A 
Now he worked and saved his money so that one day he might send  
 
My daddy 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  
A 
Down that old hillbilly highway  
 
That old hillbilly highway  
                   D7 
That old Hillbilly highway  
            A 
Goes on and on  
 
SOLO

Now 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  
 
Down that old hillbilly highway  
 
That old hillbilly highway  
                   D7 
That old Hillbilly highway  
            A 
Goes on and on
