The Kinks, always a good choice Tom
Tho' I am quite particular to some glam stuff....Marc Bolan's Rexmas Bop and Slade's MEEEERRRYYYYY Christmas EveryBOOOODYY! :P
Mahalia Jackson's Silent Night is one of the most beautiful I've ever heard as well as Karel Gott's Adeste Fideles and to finish my selection off, some Mistletoe and Wine from Sir Cliff R.
