Amusingly, the song has been translated in time & space as well as in language. "Podmoskovnye vechera" means "evenings in the suburbs of Moscow".

The second stanza is beautiful in Russian, but untranslatable. Literally it says "The river moves and doesn't move, all of moon silver. It's hard to express, and not to express, what is in my heart." The lover's hesitation between speaking & remaining silent is likened to the intermittent motion of the water's surface. (Or at least, so I understand it -- I don't know much Russian.)
