Here are my questions and the answers from the website owner:
1. What is the actual title of the Ukranian/Russian original? Or is it, like many folk songs, known by more than one title?
First of all, thank you for visiting our site! We are really happy to know that it has been so useful to you. As far as we know, the title of the Ukrainian/Russian original is "A gde zh gusy" (in the original spelling: ?

?

?). This is the original page (in Russian) of Sholohov's "And Quiet Flows the Don" where the song is quoted:
http://lib.rin.ru/doc/i/5207p5.htmlOf course, like most folk songs, this song may be known by different titles, or also by no specific title at all: in this case, the first
verse is usually taken as "presentation title". I think you may refer to this song as "A gde zh gusy" (Where are the ducks?).
2. Are there any known recordings, downloadable or otherwise obtainable, of this original song? I am particularly interested in a rendering by one of the really excellent Russian male choruses.
We do not know. We think you should address the Smithsonian Institute:
