I think I read that the original song had over 80 stanzas. Artists pick and choose from those, so that the lyrics are not necessarily the same from version to version.
I particularly like the Jeff Buckley version.
That may be true, but this priest created his own lyrics especially for this occasion and couple. Unfortunately, the acoustics are terrible. Fortunately, Kirkwood has deciphered and transcribed them for us, in the post just above yours.
