GO 'LONG MULE
As sung by Uncle Dave Macon

I've got a mule, he's such a fool
He never pays no heed
I build a fire right under him
And then I made some speed

CHORUS: Oh go 'long mule, don't you roll them eyes
You can change a fool, but a doggone mule
Is a mule until he dies

Oh Jerry Aches and Dottie Paines
Got married on the train
And now they say those Georgie woods
Are just full with aches and pains

I drove right down to the graveyard once
For to see those pals of mine
But when that black man crossed my path
I sure, Lord, changed my mind

I bought some biscuits for my dog
And I laid them on the shelf
I slept so hard I shot my dog
And eat that bread myself

A man way down in Georgia
Pulled his gun on me
But when he fired that second shot
I passed through Tennessee
