"one of these days god is gonna cut you down...."

my husband wants this song and he has it stuck in my head. we saw it on a commercial and the music is old railroad tune but the lyrics go somethin like this:

the rambler the gambler the backrider(?)........one of these days god is gonna cut you down, one of the days he'll cut you down


cant remember the commerecial it was for, just remember a persion hanging and the music sounded like somethin from the old railroad days any help would be greatly appreciated.

nvm....we found it. it was johnny cash "gods gonna cut you down"
