Thought that would catch your eye....
We've recently established a Celtic-influenced session here in Bergen. It's on every Wednesday at about 10 p.m in a pub called Finnegan's Wake (original) downtown. The atmosphere is unpretentious, but there is true enjoyment of playing, and the beer is free for musicians.
If your situated in the area, or maybe further down the West-coast (e.g. Stavanger), try to visit us sometime. This also perpetrates to "the Dubliner"'s crew in Oslo, whenever you visit our sunnt town. (You're hearing this John?)
