Clearly our experience differs.

Sometimes in a situation where there is division a seemingly innocuous song can become explosive. Or a song that has passed the its-history-now test Marje proposed can be re-ignited by circumstances.

For example at the time of the Miners' Strike, Byker Hill.

An example of the first was a modern song written about the Boer War, General de la Rey. Not a word in it about modern South Africa, it was about fighting the British Empire, but that didn't stop it being used as a kind of anthem by revanchist Afrikaaners.
(Even though Koos De La Rey wasn't at all that kinf of Afrikaaner.)
