This may be a tough one. I was watching Vietnam in HD on the History Channel and there was a brief segment involving Christmas. I believe there were three song snippets played and I was wondering about the artists. I would love to find out who was singing those tunes. The songs are played in the "A Changing War (1969-1970)" episode @ 20:10. The songs are Jingle Bells and it sounds like its followed up by Away in a Manger and Silent Night. It might even be the same choral group.
You can see the episode here...
I checked the soundtrack on Amazon and didn't see any Christmas music listed.
I hope someone can provide some info.
Thanks in advance.
