My son went to a gig last week by some Finnish madmen called Turisas, who dress up like beserkers and wear face paint a la Braveheart. I had a look on YouTube and they have a girl playing four row accordion and a lad playing fiddle. I thought at first that the attractive tune was from the Finnish tradition but it turned out to be "Ra Ra Rasputin, Lover of the Russian Queen". No doubt in 100 years this will be a much appreciated cornerstone of the Finnish Folk Revival. I look forward to a UK equivalent.
