I don't know if it was authorized, but the wife of my Grandad's employee at the old auto salvage used to sing it to me. (she referred to herself as colored, not black.) When I was very small, she was singing it, & I asked her what's "darkie." She answered, that's ol' time for colored folks," and went right on singing.
My parents took us to a little church in Sapulpa, Oklahoma, called the Beams of Light Tabernacle, until I was about 6. We sang logs of songs about Light in Sunday school, the regular service, and also during vacation Bible school. They are some of my favs. There was one fav which I did not see in print until I was a few decades into adulthood. I only remembered the chorus:

   Sunlight, sunlight, in my soul today;
   Sunlight, sunlight, all along the way;
   Since my Saviour found me and took away my sins;
   I have had the sunlight of His love within.

I sometimes visit a local church which has this in their very old, but wonderful, hymnal.
