I got involved in 'Folk' song in the mid sixties (In UK) and thoroughly enjoyed singing songs like 'Dublin in the Green' and other
similar Irish Rebel songs , as did all my Folkie mates . They were GOOD choruses and were sung in Drunken nights in The NAAFI on a lot of Military bases .
That all changed when the Civil Rights Movement in Northern Ireland was Hijacked by the I R A in 1969 . Who wanted to sing about 'The Glorious Struggle' when a good percentage of your audience could well have loved ones serving in Belfast , and being shot and bombed by 'The Boyos' !
Now that there is a sort of peace in Ireland , it is not so bad to sing some of the songs , but as has been pointed out , there are too many memories of stupid things done by ALL participants in 'The Troubles' , so a degree of circumspection wold seem to be called for .
A Bloody Shame in MY opinion , as they are STILL Good Chorus songs !
