Jimmy Fallon's gone and ripped off David Letterman's Christmas tradition and thrown an Anna Kendrick into the mix for good measure.

The late night hots revived his classroom instrument music session with The Roots for a festive holiday special this week, this time joined by Kendrick and Darlene Love for a rendition of Love's 'Christmas (Baby Please Come Home)'.

If this is family to you, that would be because Love's performance of the song was David Letterman's annual holiday tradition since 1986 and although Love said that she wouldn't sing it on late night TV again out of loyalty to Letterman, it appears her tune has changed since 2015.

Not that we're complaining that much. It's still one banger of a Christmas song.
