Tango and Kalevala

During my research about Finnish social culture I found this, very biased video, but the interesting part is somewhere in the middle - about Finnish tango: http://www.liveleak.com/view?i=fc3_1190920643

Besides I'm trying to find Finnish national epic Kalevala in Latvian online. On my way I found out that "Hobbit" and "Lord of the Rings" is inspired by Kalevala. http://en.wikipedia.org/wiki/Kalevala
