This is a Soviet hymn, recorded by all USSR pop stars right after the USSR collapsed, in 1991. They thought this music and words would be now a part a history, because just a little bit later a new hymn appeared, with another music and words, so all people of Russia thought they are now living in a democratic state, without
traces of Soviet Union. But then a few years later, after the free goverment turned to be not so free, censorship in Mass Media appeared and.... Soviet Hymn was restored. Now, in modern Russia the hymn is being sung on the music of the Soviet hymn. Welcome back to a new USSR - Russian Federation.
