Sirkkojen Tanssi C:Viljo Vesterinen
This is a jenkka composed by Finnish accordion legend Viljo Vesterinen 1907-1961.
The title translates as (The) Crickets’ Dance.
A jenkka, or saksanpolkka (Saxon-German - polka) is the Finnish form of the Schottis (sottiisi), which has "jumps".
The first setting is a basic one, followed by one that reflects Vesterinen’s, often chromatic, accordion runs.
The original recording is played in a lower register and in Bb minor, though it may be a result of the recording speed (but not unlike Vesterinen to play in such keys).
The third setting is from Norrbotten in Sweden, and would qualify for a separate tune submission, but there is obviously a relationship both in melody and title (Sirkoijen tanssi - the Meänkieli [Finnish dialect spoken in northern Sweden] equivalent of standard Finnish). This setting comes from the band J P Nyströms (named after a harmonium building company) and on their album "Låtar i Norrbotten" (tunes in Norrbotten).
There is a similar version played by Jeff Anderson here:
Anderson suggests that the tune was composed by Albert Israelsson, who was a singer and player of fiddle and chord zither, from Gällivare in Norrbotten.
A bit of a chicken/egg situation. The two versions are obviously related, but whether Vesterinen based his composition on a tune doing the rounds, or Israelsson played a simplified version of Vesterinen’s composition is open to speculation. It is, however, unusual to name traditional style Swedish tunes in such a manner. "Schottis från Norrbotten" would be more typical - "efter (or av) Albert Israelsson" even more likely.
This does make me think that it started out as a Vesterinen composition and went through the "folk process", but it’s only a hunch.
The 4th setting is an adaptation of the tune by the northern Swedish band "HiLLa", with words by the band’s singer, Helena Ritzén (called "Pikku oja/Lilla beck" [little stream]).
