In 1970 when I was expecting my first child, I was especially touched by a Barbara Streisand song, "The Best Gift"
. It had special meaning to me because I'd been told I could never have children and was only able to get pregnant with my baby because of fertility therapy. Shawn was born December 5th, so he really, really was MY best gift. The song still brings tears to my eyes.
Love Kathy Mattea's rendition of "Mary, Did You Know?"
As for groups, I like Alabama. Especially their 1985 album called "Christmas." There's nothing more cheery and Christmassy as "Thistlehair the Christmas Bear" on that album.
