John Hardly, you have just described what I've been calling, "Mom's church"... she went (and took me when I'd go) to the Little Zion Church at Jeff, Kentucky, a two-mile walk down the railroad tracks from home. They used a book (giving only lyrics and meter, and held only in the song leader's hands) called, The Sweet Songster. The song leader decided upon the song, say, Amazing Grace, picked a tune to fit the meter (C.M.) and sang out the first line, then "lined out" the second line and everyone, now aware of the tune chosen, would join in, and so on to the end of the song. The tune usually chosen for "Amazing Grace," in the Little Zion was quite different from the usual one.

The Sweet Songster gives six verses:

1) Amazing grace, how sweet...
2) Twas grace that taught my heart to fear
3) Through many dangers, toils and snares
4) The Lord has promised good to me
5) Yes! when this flesh and heart shall fail,
And mortal life shall cease,
I shall possess, within the vail
A life of joy and peace. (then my favorite verse):
6) This earth shall soon dissolve like snow,
The sun forbear to shine;
But God, who sent me here below
Will be forever mine.
(this vs. not in the book but he lined it out anyway):
7) When we've been there ten thousand years
