The tune sounds like a pastiche of a couple of other well-known bluegrass/oldtime gospel songs. Mainly, "Leave it There," widely recorded and generally attributed to Albert Tindley. Even Willie Nelson has sung it (the original, not the parody!), on Garrison Keillor's Prairie Home Companion radio program. The lyric, though, is completely unrelated.

The other tune this song leans on will come to me eventually.....
