I cannot. The voice-over confounds my half-deaf ears so that I cannot understand what is being sung. And a foreign language being sung doesn't always parse easily for me, and it's not a song I am familiar with. And when I google on what they say (minus the parenthetical comment): "Turn Your Gaze, Industrious Workers! (In Russian, With Translation)" I get one hit... today's Woot!

But neither did I hear anything that made me think, "That's not really Russian". Hope someone who knows something responds -- I'm now curious too.
