Interesting to see the various messages in this thread over the years. Seems as if nobody (and I'm no exception) can remember more than a few lines of the "unofficial" words we used to sing as kids. As has been noted, Guest, Julia, way back in May '04 came up with a translation of the German words used in Lohengrin. I'd seen a translation of them myself somewhere and though I can't remember if they were exactly the same as those she quoted, the sense of them is certainly the same.

Also, Lucius mentioned above that the Bridal Chorus from Lohengrin is used as a recessional and that the traditional processional is Mendelssohn's Wedding March (from the Incidental Music to A Midsummer Night's Dream, as stated). Actually the opposite is true. The Bridal Chorus was written with words sung by the opera chorus, and starts with the tune of "Here Comes the Bride." The Mendelssohn was written as strictly instrumental music to be played during breaks in the play.
