David Allan Coe wrote and recorded a song called I HEARD OKLAHOMA CALLING ME. It's on the Bear Family collection "A Matter of Life & Death" (1987):

In my broken state of mind,
I tipped the bottle one more time
Then told the world goodbye I used to know.
Oklahoma's callin'. I can feel it in my veins.
Yes, Oklahoma's where I want to be.
Somewhere in the bottom of this bottle in my hand
I heard Oklahoma calling [me]....
