Säkkijärven polkka, the program's signature tune, has a history of its own and is probably one of the most recognized tunes in
Säkkijärven polkka is based on a traditional Finnish tune from Säkkijärvi village (now part of Russian Karelia). The performer was Viljo Vesterinen, the famous accordion artist, recorded by the Finnish Broadcasting Company in June 1939. The tempo of the music was fast enough and the melody varied enough to foil the frequency used by the Red Army. The polkka was played about 1500 times before the mines had been detonated or their batteries were spent.
