Dear Brakn, This may not be any help, but a Net search turns up this. The song seems to be a favourite of the Mormons (if these people are Mormons):

I want to reprint a poem that nearly sixty years ago was repeated to me in Idaho, or, rather, it was not repeated as a poem; it was sung as a song by the late Francis M. Lyman.

It so happened that from Tooele I had to travel thirty-six miles to Salt Lake City and then on through Davis County, Weber County, and up to Brigham City, and then two and three-fourths days' journey west out to Oakley, to what was then a branch of the Grantsville Ward of the Tooele Stake of Zion over which I presided. (The first motion I made as an apostle was to present that whole country to the Box Elder Stake of Zion.) Now, when I was on that trip, Brother Lyman sang a song to me, and that very night I sat down and asked him to repeat it to me while I wrote it down, and the next day I learned it:
Let each man learn to know himself;
To gain that knowledge let him labor
To improve those failings in himself
Which he condemns so in his neighbor.

and so on. This is probably not much use -- but a gesture to let you know that no posting is completely unrecorded, and no hope... (I feel a song coming on).

Yours, Peter T.
