I made a big research about this very unique song.
I found over 50 texsts to this melody, in more than 30 languages.
Some of them translations, most of them originals, mainly of left or extreme left movements, civil or armed, all over the world, starting 1914 and intu the 21st century.
My conclusions about the creators of the original song:
Lyrics - Pyotr perfyonov. (approved by a Russian jury).
Music - Aturov? Impossible. His name is mentioned for the first time in 1929, when he introduced the song to Alexandrov, while lyrics to this melody were written 1914 to 1920 in Moscow, Siberia and Ukraina. It seems the melody was well known then all over Russia.
Some sources say it is originated in the 19th century. I beleive it’s so.
