Darlene blows away the crowd with her final Late Show performance of "Christmas (Baby Please Come Home)."

Sandra and I have been talking about this for weeks.

For the last 28 years, Darlene Love's Christmas gift to you was her performance of "Christmas (Baby Please Come Home)" on David Letterman's late-night show. "You, the David Letterman show, started this connection," Love told Letterman on Friday, before her final appearance on Letterman's "Late Show." "I didn't sing this song that much. [...] The more we did it on the show, the more people wanted me to do it."

"I would never sing it again on another show," Love clarified on Friday. "This is where it will end. But I will sing the song again." Please do.
