The first time I heard this song was a day or two before the Great American Power Blackout of November, 1965.
Nobody knew what the hell was going when the lights went out seemingly everywhere, and the only explanations that seemed plausible to my age cohort were Russians or spacemen. It took several hours to determine the actual cause.
I vividly recall a radio newsman (operating on battery power) reporting that lights were out in San Juan, Puerto Rico, as well.
(This turned out to be true but brief and coincidental.)
