Time for something completely different...
I like to think that the FMS provides a welcome break from the endless round of Christmas hits that get played every year around this time. This then is the nearest we are going to get to a Christmas song. Which it isn't really, but as it samples 'jingle bells' and mentions Christmas the timing is at least correct and the video images appropriate. 
From the 1971 LP 'Blue' Joni Mitchell sings 'River'.
There are many covers versions but none come close to the original. This is real stardust...
