One of my all time favourites is a 16th century French carol "Un flambeau, Jeannette, Isabella (Bring a torch, Jeannette, Isabella)" which I discovered years ago when searching the web for Christmas music to use on a web site. I found a lovely recording on YouTube
here, and information about the carol plus lyrics in both languages are
here.
I also love the Cherry Tree Carol (especially when sung by Joan Baez), and the Coventry Carol.
A rather special carol which is very appropriate this year is Silent Night, which was was one of the carols sung by the British and German soldiers in the trenches during their Christmas truce in 1914, 100 years ago - in its way a very special Christmas miracle, which always brings me close to tears.
I Saw Three Ships is another one brings back very special memories of a visit I made in December 1993 to Jamestown, Virginia, USA, while attending a needlework seminar in nearby Colonial Williamsburg. Jamestown was America's first English colony, predating the Plymouth, Massachusetts colony by thirteen years. The Americans honour these early pioneers with a reconstruction of the settlement on the original site, and replicas of the three tiny (and they were
tiny!) gallant ships that carried them on their long voyage are moored in the harbour there. They sailed from London on 20th December 1606 and they were still sailing off the coast of England on Christmas Day. Their voyage took over four months and they arrived in what was to become Virginia in April/May 1607. In memory of my Jamestown visit, I designed and stitched a sampler combining details of the three ships with words from one of my favourite carols.
