Well, given our history of centuries of colonial oppression, wars, “the” famine (in reality there were many but the 1845-49 one was the most documented), grinding poverty, misery, hunger, disease....etc etc.
...it’s sorta not surprising that all our traditional music lyrics are sad, sorrowful ones. The Ireland of today doesn’t really lend itself to such lyrics, except for homelessness which, apart from Covid-19 is the biggest challenge we face.
I have to admit that I was never the biggest fan of trad music - sure, a live session down the pub with a good band and the drink flowing (in my drinking days) can be great fun, but I wouldn’t go out of my way to listen to it. My eldest sister plays the bodran and accordion with an expat Irish trad group in Canada.
My late mother knew quite a few trad ballads - and sang a few of them beautifully - Carrickfergus and The Spinning Wheel come to mind.
