Okay, I'm back with my nomination:
Don't Cry In Your Sleep by Jim McLean
It's in DT here .
Why?
(1) Trad sounding diction consistently all the way through, no modernisms, and (AFAIK) historically accurate...
(2) Telling details: you can hear the children singing, see the flames leaping, feel the defeat and despair of men huddled like cattle...
(3) The song isn't just a snapshot of a single idea, but runs through a series of emotions: from nostalgia to fear and grief, to bitterness and anger at the men who didn't resist (what could they do?), to a glimmer of hope at the end...
(4) And a haunting rhyme scheme that breaks away from the doggerel effect the tune might lead to. Great song, Jim.
