I tried to make a post here about a week ago but the site didn't seem to want to let me.
I was surprised to see a thread on Irish music in here, it's not in general a common topic on the internet in my experience.
Just thought I'd mention some of my favourites my self. I'm a big fan of the Dubliners and Christy Moore, the best artists about at the moment in my opinion.
My favourite songs would have to be Dear old Skibbereen, Spancill Hill and the famous Fields of Athenry.
Also Joxer goes to Stuttgart by Christy Moore is a great one though the English might not relish it.
