There was that National Geographic "Beyond the movie - LotR" release ages ago, but I've watched it again recently and I can't get rid of the sudden need of hearing that "Karelia-theme", only clean (with no narrator's voice).
I think it may be one of Kalevala runes sang by some woman. It can be heard when they mention that really old Finn - a treasure chest of their culture I woul call him
Is there any chance to get an mp3 (or whatever)of that????
