You will note that I did not contribute to the alleged Celtic/Brito-centric leanings of this forum by pointing out that yesterday was the anniversary of two events.
The more recent was the death of George VI, who was succeeded by his daughter, Elizabeth II, 50 years ago. (Political aside, "Hang in there, Queen Bestie - yer a heluvalot better than that ejit son of yours!")
The other is, for me, more notable as the "song" was first taught to me as the pipe "tune" - The Rape of Glencoe. The song the Massare of Glencoe tells the tale (albeit a little one-sidedly) of events happening in that valley on February 6, 1692.
Combine that with Davey Steele's Beaches of St. Valarie and No Man's Land and you've got a depressing tio of historically based songs.
