New York City has repealed a 91 year-old law that prohibited people from public dancing at establishments that did not have a cabaret license. Under this law, only 104 establishments in New York City allowed dancing.
The law was introduced in 1926, during Prohibition, as a way of controlling illegal venues. The law has been very loosely enforced throughout the years, but now will no longer be an impediment to those who wish to dance. (source) 5:02 p.m. ET November 28, 2017
