A celebratory Rébus!

Let's celebrate as Mono-Monday reaches 100!  I meant to try and work out how many I have done but haven't got time!  My first attempt was Mono-Monday - water which was really well received!

 This 100th blip is hosted by Skeena!  Thank you very much!

"A rebus is an allusional device that uses pictures to represent words or parts of words"  ".....speaks to the beholder Non verbis, sed rebus, which Latin expression signifies "not by words but by things".."  (Wikipedia)

Can you work out what carols these pictograms refer to?  This was part of our Christmas quiz at the Friday group!  Answers tomorrow!
