King Pharim which is sung by Barrand & Roberts and by the Watersons and The Ditching Carol which I have heard by the Watersons are pretty old and certainly not "done to death" by my definition of the term. Songs in a little wider circulation are Carol of the Birds and Bring A Torch Jeanette, Isabella. There are a lot of good songs on the Patons & Barton & Para Christmas CD "Twas On A Night Like This". One of my favorites from this CD is "Sweet Lamb".   Steeleye Span and Maddy Prior have recorded some interesting Christmas music. One of my favorites from them is Gaudete. I also like "There Was a Pig Went Out To Dig" which is on one of the Christmas Revels CDs. The Christmas Revels have several recordings of "not so usual" Christmas music. "Nowell Sing We Clear" is the Barrand & Roberts Christmas recording.
