Ah, “12 Days of Kwanzaa” is an old favorite of mine. LOL
For serious music, Amy Grant has two Christmas albums, either of which are great. The album “Tennessee Christmas” may be the best Christmas album of all time. Be sure to check those out - there are too many good ones on them to single any out.
Also, check out the Vince Guaraldi Trio album (Charlie Brown Christmas). “Christmas Time is Here” with the children’s choir is my favorite.
