"The church musician Primus Leppänen (1872–1934), who was the cantor of Säkkijärvi, wrote the polka notes on paper, dutifully marking it as a folk tune.
The recording was not an accordion solo, but the chorus of the song was sung by Kurt Londen (under the pseudonym Ilmari Rae) based on the lyrics written by RR Ryynänen.
During the Continuation War, the Finnish Army discovered that the retreating Soviets had scattered radio-controlled mines throughout the re-captured city of Viipuri.
On August 28, 1941, the combat engineers found triggers packed in rubber bags in Antrea from a 600 kg explosive charge installed under the Moonlight Bridge.
The Communications Department ordered Captain of Engineering (later Professor) Jouko Pohjanpalo to take them to Helsinki as a matter of urgency, and with the help of YLE, they were dismantled and investigated.
[citation needed] On September 1, the General Staff in Vyborg received one broadcast van from Yleisradio,[2] capable of transmitting over the frequency used by the mines.
[clarify] On September 4, it was noticed that Soviet troops were continuously transmitting the triggering triads on the same transmission frequency.
There was a great fear that the internal combustion engines running the broadcast van generators could fail, and therefore the military quickly ordered additional 50-watt transmitters[5] from Helvar, which were delivered as early as September 9, 1941.
