The Madness of the Dance (2006)

In the middle ages there was an outbreak of dancing manias in Europe that lasted hundreds of years. In the 20th century thousands of Chinese men and some women thought that their genitalia were vanishing, while schoolgirls in Belgium thought that they were being poisoned by a certain brand of fizzy drink. Looking at these various cases, and more, the professor (Maxine Peake) takes us on a musical journey through mass hysteria.
