1986 was the first year that R&B singer Darlene Love performed her barn-burning rendition of "Christmas (Baby Please Come Home)" on David Letterman. Remind yourself:

And though she's visited Letterman to reprise the song ever since, it was questionable if Darlene was going to show up for this year's holiday show. However—probably because she knew Letterman was retiring—she did perform it, and if you missed it last Friday, here it is in all its glory.

Kind of different from the 1986 version, huh?
