Thinking further about this, Ireland has a rich back catalogue of folk songs, many of which are pro Republican, commemorate past atrocities, injustices, potato famine, etc. I assume these are still sung in the clubs and pubs with no qualms, in the same way people in England seem happy to sing wartime songs (even Rule Britannia) as part of nostalgia. Does the passage of time lessen the contentious nature of certain songs, so rebel songs like The Wearing of the Green are no longer regarded as inciting hatred or insurrection?
