Bev and JerryHennesy's, I'm afraid, is close.
Michael,Try Marrinan's (in the main street) during the day - the same system tends to operate. As the town gets noisier, the singers move further and further out - sometimes ending up in Gleesons or McCarthy's of Coor (which may be difficult to find on your map), in the small hours.
INstrumental music sessions are all over the place, all the time.
See you there
