The Penguin Book of Christmas Carols

I bought this book way back in the late seventies whilst on holiday in Portsmouth, England with the intention of getting carols from it for singing within the family circle at Christmas time. It is a very scholarly work whereby each carol is scored for at least four voices and sometimes there is also a descant/trumpet line. I never used it for my initial intended purpose but is the source from which I was inspired to do "Away in a manger" with two penny whistles with the Klingende Runde für jung und alt at a Christmas concert in Meyenburg, Germany.
