The Little Drummer Boy live duet by David Bowie and Bing Crosby was an absolute genius creation of old and new that hit it the mark on a live broadcast. You have to understand that Bowie was a space cadet at the time.
Silent Night - Barbra Streisand
Rockin' Around The Christmas Tree - Brenda Lee
The Beach Boys - Little St. Nick
Most prefer John Lennon's Christmas Song, but I prefer Wonderful Christmas Time by Paul McCartney
Try a most unique version - Santa Claus Is Coming To Town --Frank Sinatra & Cyndi Lauper. That was cut after the Bing / Bowie smash.
"Baby, It's Cold Outside" ? A lot have tried that one. I like two versions, one by Eartha Kitt but the Leon Redbone and Zooey Deschanel duet version just blows me away. You'll remember Zooey singing a solo version in ELF.
Life's not the breaths you take, the breathing in and out that gets you through the day ain't what it's all about. It's the moments that take your breath away.
