Oh, Holy Night
The Little Drummer
Hallelujah Chorus

Most French carols. They're the most muscular thing the French do. (Yeah, excepting that!)
but Not The Little Drummer! That's my cousin's favorite though.
Although a singing dog, I don't think Snickers understands the concept.

"Santa, Baby" - either Eartha Kitt or Madonna.

My very favourite Christmas tune of all time is "Do You Hear What I Hear?" as sung by the incomparable Bing Crosby in 1963. Written during the Cuban Missile Crisis of 1962 and being released only a few days before the assassination of President Kennedy, that beautifully-crafted number struck a literal chord with the American people. It became a massive hit for Mr Crosby and is still being played on radio every Christmas season almost a half-century on. I have ever such fond memories of hearing it wafting from Mum's old 1940s Bakelite radio in our tiny North Camden NJ flat as she puttered about, whistling along and making that humble home ready for Christmas on a poor pubmaid's salary. Thank God and Bing Crosby for collaborating on such a sweet and splendid melody and God bless Mum for making it so memorable all those long decades ago. A most Happy and Fire-Safe Christmas, ev'rybody!
