I was able to check the BCEFA Carols for a Cure cds from Volume 2 to 19, and the song isn't on those CDs. (There are versions of Hark the Herald Angels Sing on Vol 6, 9, 12, 13, 14, and 19, but not the one i'm looking for...).
So it might be the cast of Les Mis on Volume 1 (1999). I can't find a sample of the song anywhere (spotify, youtube, Amazon, iTunes, etc).
Can someone please check Volume 1 of BCEFA for the version of Hark The Herald Angles Sing i've described above?
Thanks so much!
