But this was not one of those 80s raves that began in a remote layby and ended in a muddy field.
Rather it’s one of the oddest epidemics to be recorded in world history.
And it happened 500 years ago this summer in the French city of Strasbourg.
It was there over the course of three roasting-hot months in 1518 that several hundred people developed a compulsion to dance.
The dancing went on and on until – to the horror of the crowds who gathered to watch – some of them collapsed and perished on the spot.
Just what was happening?
According to an account written in the 1530s by the irascible but brilliant physician Paracelsus,the ‘dancing plague of Strasbourg’ began in mid-July 1518 – when a lone woman stepped outside her house and jigged for several days on end.
Within a week dozens more had been seized by the same irresistible urge.
The rich burghers who ran the city were not amused.
One of them – writer Sebastian Brant – had devoted a chapter of his moralising bestseller Ship of Fools to the folly of dance.
Mystified by the chaos in the streets – he and his fellow city councillors consulted local doctors who in keeping with standard medical wisdom declared the dancing to be the result of ‘overheated blood’ on the brain.
