The Brothers Four: Merry Christmas
When I was growing up, one of the traditional parts of our family Christmas was listening to (vinyl) Christmas records. Some were good, some were just "OK." My favorite, by a long shot, was Merry Christmas by The Brothers Four. Unfortunately, my parents got rid of their Christmas albums, and the vinyl originals are now apparently "collector's items" that I've seen priced over a hundred dollars – not something I would consider spending for Christmas music! I was glad to see that the album was re-released on CD.
If you enjoy male vocal harmonies, I recommend giving the Merry Christmas samples on Amazon a listen. Hopefully you'll like their music as much as I have over the years!
