After all these years, the Mongol Internationale has finally been uncovered, even if it's just a short version.
For those who don't know, this was the first anthem of the Mongolian People's Republic. When the revolutions after the First World War came to a close, the communists only managed to gain power in three countries: Russia, Tuva, and Mongolia. When Russia united with three other republics, the Soviet Union was formed and adopted the Internationale as its anthem. Tuva and Mongolia made the Tuvan Internationale and the Mongol Internationale in honour of this. These are the "Three Internationales" mentioned in the Tuvan one. Mongolia replaced its anthem in 1950 and the Mongol Internationale fell out of use. Now we finally have a vocal recording of this mysterious anthem.
