Den heter Can-can.
The can-can (or cancan as in the original French; French pronunciation: [kɑ̃kɑ̃]) is a high-energy, physically demanding dance that became a popular music hall dance in the 1840s, continuing in popularity in French cabaret to this day.[1] Originally danced by both sexes, it is now traditionally associated with a chorus line of female dancers.[2] The main features of the dance are the vigorous manipulation of skirts and petticoats, along with high kicks, splits, and cartwheels.
Den musik som de sjunger vid denna tidpunkt är också den traditionella musiken från den dansen.
