Great old song. I sang for several years with a barbershop chorus here in Richmond. This was one of our fav songs to perform.

"All God's children got someone to love,
When it's darkness on the delta
Only heaven is in sight
When it's darkness on the delta
Let me linger in the shelter of the night."
