Hi JDL,
Here's what I was able to dig up, in terms of Lyrics. This is from the May 10, 1869 issue of The New York Times!
"Bless'd be thou, the God of Israel,
Thou our Father and our Lord;
Bless'd thy Majesty forever,
Ever be thy name adored.
Thine, O Lord, are power and greatness,
Glory, victory, and thine own;
All is thine in earth and heaven
Over all thy boundless throne."
Here's another version I found:
1. Blessed be Thou, O God of Israel, Thou our Father and our Lord! Blest Thy majesty forever, Ever be Thy Name adored!
2. Thine, O Lord, are pow'r and greatness; Glory, vict'ry are Thine own; All is Thine in earth and heaven; Over all Thy boundless throne.
3. Riches come of Thee, and honour; Pow'r and might to Thee belong - Thine it is to make us prosper; Only Thine to make us strong. Amen.
I'll see if I can dig up more clue about the music. Hope it helps
