I'm standing in the post office listening to the piped Greek versions of the old familiars, and enjoying the way the locals are whistling and clicking along: Jingle Bells, Ave Maria, Greensleeves, Silent Night, God Rest Ye Merry Gentlemen ...

And all I can think of - or hear - is the incomparable Tom Lehrer's take on the commoner carols.
