Russia wasn't completely cut off from decadent Western pop culture during the Cold War! From the description at Dark Roasted Blend:
Not sure how this passed the communist censorship, but the world-famous Moiseyev Ballet in Moscow performed this dance not only during their trips to America in the 1960s but also at Tchaikovsky Concert Hall in Moscow in 1962. They did call it a "parody dance" in the official program - but they still have too much fun dancing it!
