Dear Jack,
I agree with you that, generally speaking, Irish themed pubs abroad tend to be rather dire and if there is music it, is rarely "live", but is either on tape or CD. There is no mention of music on the Rocky O'Reilly's website, but I will check out the other two in the hope that someone in there may know where the local musicians hang out. While I am Irish and enjoy playing Irish/Celtic music with my friends, I don't hunt for Irish music sessions when I travel abroad. I will definitely check out that music store you have suggested. Thanks.
Best Regards,
Anne XX
