Το θέμα της άσεμνης μουσικής και χορού είναι πολύ παλιό, από την εποχή του waltz, ή και πιο παλιά..


There was still much opposition to this “immoral” dance. Many dance masters complained about it as they saw the waltz as a threat to their profession with the easy to learn steps being able to be taught quickly as opposed to the extremely difficult moves of dances such as the minuet. Religious leaders, along with many in court circles and society still held out against the waltz, citing the closeness with which the dance was performed as highly immoral. Funnily enough, Queen Victoria loved the waltz and was an excellent ballroom dancer. Like most things though, the more the older generation and the moral upper echelons complained about the waltz, the more popular it became
