AHA! here is the lyric I found to the tune of "Here comes the Bride" as I suspected from the opera Lohengrin by Richard Wagner
This is a translation appearing in the Franklin Square song collection circa1885

Guided by us, thrice happy pair
Enter this doorway, 'tis love that unites
All that is brave, all that is fair
Love now triumphant forever unites

Champion of virtue boldly advance
Flower of beauty gently advance
Now the loud mirth of revelling is ended
Night bringing peace and bliss has descended
Fanned by the breath of happiness rest
Closed to the world , by love only blest

Guided by us, thrice happy pair
Enter this doorway, 'tis love that unites
All that is brave, all that is fair
Love now triumphant forever unites

Whew!
