This is just wonderful! It features seventeen artists, and every single song is unique and interesting. Rufus Wainright and Sharon Von Etten could be singing sixty years ago in Baby, It's Cold Outside. It is a rare treat to hear O Come, O Come, Emmanuel sung by Punch Brothers. Y La Bamba performs a delightful Senor Santa. The Shins do a version of McCartney's own Wonderful Christmastime, while Paul sings The Christmas Song, with Diana Krall on piano.
