Here's Ernest Tubb's version (1946), copied from notes to a country music collection set released in Japan:

    DRIVIN' NAILS IN MY COFFIN

My sweetheart has gone and I'm so lonely
She said that she and I were through
So I started out drinkin' for pastime
Drivin' nails in my coffin over you

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

Ever since the day that we parted
I've been so sad and so blue
I'm always worryin' about you, love
And I just can't quit drinkin' that old booze

Now you've turned me down, you don't want me
There's nothin' now I can lose
I'm just drivin' those nails in my coffin
And worryin' my darlin' over you

~Masato
