Lyrics and chords copied from the Cowpie site:

DRIVING NAILS IN MY COFFIN
(Jerry Irby)

My [C] sweetheart is gone and I'm so lonesome.
She said that she and I were [G] through.
So [C] I started out drinking for pastime,
Driving nails in my [G] coffin over [C] you.

I'm just [C] driving nails in my coffin
Every time I drink a bottle of [G] booze.
I'm just [C] driving nails in my coffin,
Driving those [G] nails over you.

Every since the day that we parted
I've felt so sad and so blue
I'm always worrying about you, love
And I just can't quit drinking that old booze.

I'm just driving nails in my coffin
Every time I drink a bottle of booze.
I'm just driving nails in my coffin,
Driving those nails over you.

[Recorded by Ernest Tubb and others.]
