I see the moon and the moon sees me
God bless the moon and God bless me
There's grace in the cabin and grace in the hall
And the grace of God is over us all

I see the moon and the moon sees me
The moon sees the somebody I want to see
God bless the moon and God bless me
And God bless the somebody I want to see

I didn't find Jean Ritchie's version in the thread; maybe I missed it. Her note above says she wrote the tune. It seems some others added or changed lyrics based on her version.
