Good job, friends and followers!
The most commonly selected version of Little Drummer Boy was sung by Bing Crosby and David Bowie in the 1977 TV special, Bing Crosby's Merrie Olde Christmas.
My personal favorite Little Drummer Boy was recorded by Bob Seger in 1987. Here's a live performance from just last month.
Six different versions of O Holy Night were mentioned. Since I couldn't choose a favorite among those, I went with another great version, sung by Josh Groban.
Finally, who doesn't love Rudolph the Red-Nosed Reindeer! (Notice, there's no question mark at the end of that sentence. If you don't love Rudolph, I don't want to know about it.) My favorite rendition is a cover of The Temptations' version, which was animated for Will Vinton's 1987 special, A Claymation Christmas Celebration. Sing it, California Raisins!
