Here's what I came up with listening to "Nobody Knows What You Do" from John Hartford's album of the same name. Flying Fish Label 1976.

I have an mp3 put up on www.country tabs...it is pretty rough, but enough to give an idea of how it sounds...v.g.

When you go down on your knees
Roll your eyes, nobody knows but you.
