Hi Andreas! Is this flexi one-sided or two-sided?
The second song is from the movie called “Tamriko’s kidnapping” sung by a trio from the Georgian Polytechnical Institute. It’s in Georgian, of course (while the first song, “Song about Tbilisi” in in Georgian and Russian. And you are right, the vocalist is Nani Bregvadze)
It’s amazing how you managed to find it – it is a rarity. There exists a series of similar records with the same picture cover, but no idea if this specifically exists in English or other language.
These ones all have different songs but were all released in 1972 by Tbilisi record plant
