Anyway, this is technically an Advent hymn I think, rather than officially Christmas. Somehow I feel like this song sounds better sung by men only, I prefer the tenor and bass voices on this one. I couldn't find a high quality version that I really liked. So here's a personal video somebody recorded at St Peter's in Vatican (Latin).
I sure do love every time they come in with the "Gaude, gaude, Emmanuel" - very full and rich sound.
Actually. I like this Enya version pretty well too, even though it directly contradicts what I'd just said about male voices. Very otherworldly, as per her style.
