Originally broadcast on December 14, 1971, Sounds of Christmas features Tony Award-winner Robert Goulet, opera singer Mary Costa, and the Mitchell Singing Boys choir. Goulet demonstrates his booming baritone on “Do You See What I See” and in a duet with Costa of “O Holy Night.” Costa shows off her soprano stylings on “Carol Of The Bells” and in a comedic medley with Bing. And the Cosby family sings a delightful rendition “Home For The Holidays.” The kids also get nice showcases, with Mary dancing the "Dance of the Sugar Plum Fairy” and Harry (on guitar) accompanying Bing on “Chestnuts Roasting On An Open Fire.”
