I'll put up three Christmas Medleys coming up to Christmas Day - One today - the next on the 18th and the third on Christmas Day. 

Here is a group of 5 tunes recorded in 2004 on a beautiful Jimmy Moon steel guitar:
The First Nowell, Ding Dong Merrily on High, Angels from the Realms of Glory,  Here We Come a Wassailing,  Hark the Herald Angels Sing.
