Apparently a lot of songs follow the same progression! Oh man, those descending fifths. ROFL.
This is rather silly... Perhaps Igudesman is bow-poking fun at the dual Russian/Ukrainian tradition of violinists and balalaika players running in families? Aside from the example in Dr. Zhivago. And the people in the video are actually violinists :-P
Classical music needs people like him and his buddy Richard Joo... check out more of their performances on Youtube. I would go for their live concerts.

And there is of course Victor Borge, who's a classic on his own... (more Youtube videos!)
I particularly liked the Beethoven and the Mozart versions. Spot on. I was hoping for a good Liszt version, sigh... too bad. I suspect his Hungarian Rhapsody has seen many renditions of randomness in Tom and Jerry already. Aaaand we have the circle of fifth again in the J.S. Baaaaaach version at 3:15...
