The one in Cyber Hymnal is the Mormon version. It's actually called "Come, Come Ye Saints." There was a song called "All is Well" in the Sacred Harp shaped note book and that's where Clayton got his tune.

The way I learned the third verse (which a friend copied for me from a Mormon hymnal) was:

We'll find the place which God for us prepared
Far away, in the West
Where none shall come to hurt or make afraid
There the Saints will be blessed.
We'll make the air with music ring,
Sing praises to our God and King,
And this above all else we'll tell,
All is Well, All is well.

A lot of Mormon songs have changed through the years, both versions are surely "authentic."
