Westport - Co Mayo
Hobans' of the Octagon. Informal session every Friday, Saturday and Sunday. Musicians and singers welcome.
Matt Molloys - In my opinion the musicians tend to take themselves a bit to seriously.
Lots of sessions in Galway City but I dont get there too often. If you get there it should be relatively easy to track something down. UNfortunately the informal session is getting harder to find. In the age of the Celtic Tiger less and less musicians seem to be interested in playing for fun.
