According to a CBS release, Love's performance of the song this Friday (Dec. 19) will be the last time she ever does it on TV. The folks at Letterman's production company, Worldwide Pants, edited together a mashup of Love's many performances of the song starting with her first time singing it for Letterman in 1986.

Does she have a favorite? As she recently told Radio.com, "There's actually two. They decided to televise the show [in 2000] to all the military [in Bosnia] and not only that, they had the Singing Sergeants [of the United States Air Force] come and sing 'Christmas (Baby')" with me. So that night was the first night I ever wore a gown. I said, 'Okay, this is going to be special.' It resonates in my head what Christmas really means: there was a war that did not happen and now we're singing to the soldiers and now the Singing Sergeants are with me, and it looked fabulous on television to see them in all their uniforms and me in a gown.

"So, that's probably the one I remember most, more than any of them. That and the very first one [in 1986]. How I looked was so funny!"
