done something wrong

(Elmore James)
The barrel-house told me
My baby caught that train 'n gone
The barrel-house told me
My baby caught that train 'n gone
It was all my fault
I musta did somebody wrong
Everything that happens
You know I am to blame
Everything that happens
You know I am to blame
I'm gonna find myself a doctor
Perhaps my luck will change
Ah, my mama she told me
These days will surely come
I wouldn't listen to her
Had to have my fun
The barrel-house told me
My baby caught that train 'n gone
But it's all my fault
I musta done somebody wrong, oh yeah
The barrel-house told me
My baby caught that train 'n gone
The barrel-house told me
My baby caught that train 'n gone
It was all my fault
I musta did somebody wrong
Oh, play the blues?
