Another version from SINSULL:
There's a big rock in the road
And it's there blocking the road
Lots of pious folk have found it
And you better get around it
There's a big rock in the road
There's a hole under that rock
And it's dark under that rock.
And they say if you fall in it
Your life won't last a minute
There's a big rock in the road

Leave the darkness behind you
Shine your light up ahead
If you don't want trouble to find you
Change the life that you've led

There's a big rock in the road
There'a a hole under that rock
It's the basement of the devil
He is wasiting with a shovel
There's a big rock in the road.

Carline, I had a recording of this dating to the late forties, I believe, on 78RPM and would love to find it again. Do you have it?

Jeri, Thanks for refreshing this. My thread on this song went unanswered a while back.
