I knew nothing of the war but I knew this song expressed something profound.
The writer/composer was 'channeling' something. Someone was whispering in his ear to tell their story.
It really conveys the tragedy and impact on regular folk caught up in the war and beaten into submission.
It still affects me when I hear it.
For another historically informed song that is somewhat similar in conveying the reality of war (and totalitarianism), listen closely to Al Stewarts Roads to Moscow.
The song reminds that the North is guilty of genocide against my people, lest I ever forget.
