The context in Soviet Russia was such that the pair were probably looking for trouble by seemingly promoting American values. So Khil decided to drop the lyrics. This is odd enough, but what about the people that invested in the small orchestra behind him and teh TV station that recorded the video? Didn’t anyone notice? Or did they think this was fun, a political statement or just another day’s work?
This is probably the only time a song without lyrics could actually have a meaning.
