I bought an album in Northern Ireland in the early 1970s by The Men Of No Property, which I've lost in subsequent moves. The songs were about the (then) recent troubles and included (some of these titles may not be accurate, but might give you words to search on):

Rubber Bullets For The Ladies, Bogside Doodlebug, Women of Ballymurphy, Ballad of Jerry (?) O'Hagan, Belfast '69, Ballad of Burntullet (sp?) Bridge, I Long To Leave Old Belfast Town, Lough Erne Fishermen, The Smuggling Song.

The album included a spoken poem, Hughes Bakery Van, and an essay entitled Why Are The British Troops Here?

I don't know where you'd begin to look, but if you can find that album, you'll have a pretty good collection of songs about the incidents that took place in N. Ireland in the 70s. If you'd like me to, I can probably remember the lyrics to a few of the songs and would be happy to post them for you.

Good luck!
