Since 1986, David Letterman has celebrated Christmas on his programs by inviting Darlene Love to sing “Christmas (Baby Please Come Home)” on his last pre-Christmas show. It’s a wonderful thing that’s grown in size and scope and power over these 28 or so years.

Letterman, of course, is retiring next year; tonight will be his final Christmas show. Love will deliver her signature holiday tune, but with Letterman’s retirement she’s announced that she will be retiring the song from television out of respect.

Tune in. It’s sure to be lovely.
