Today marks 54 years since the Great 1965 Blackout. The power didn't go instantly, instead the frequency of the alternating current dropped as parts of the grid failed and remaining generators still online tried to crank out sufficient current to keep the lights running. As radio stations were using tape decks back then, as the frequency of the alternating current slowed, you can actually hear the tape recording of Jonathan King's "Everybody's Gone to the Moon" slow down. It was a perfect song to be playing on that night, because it was a full moon.
