Kerb, I can put you in e-mail contact with "Barb Wire" and "EL Wire", if need be. These guys, and the other "Wires" camp under the moniker Camp Herring (sild). Typically, they go every other year. 2012 should be their year.
I also know of one other great BM fan in Norway. Met him in BRC in 2007. I'll skip his name for now, but he is a Reodor Pris winner, so he is "somebody" in the realm of creativity. I'll PM you.
(I grew up in Oslo.)

Elliot's Bicycle Service and Beverage Dispensary expects to be at 5 & G. Bicycles repaired, loaned and whatnot. Hours likely to vary.
