A previous thread on national anthems gave a link to http://www.geocities.com/Area51/Cavern/1026/Anthem.htm where mp3 files for a number of national anthems can be played/saved.

The one there for "USSR" is lovely, but I can't tell if it's the one wanted. The mp3 has a bit of "walking bass" that should make it fairly easily to identify basic chords.

(Note that the default filename for the USSR is "typoed" as URSS.mp3)
