Very interesting comment. I recall Zorba, but had to google to recapture the context of the dance scene which has stayed with me. It "worked for Zorba", it seems, in response to Zorba's bewailing his "loss of madness". Curious. This "passion", of the dance is/was a scary, sinful dimension of Church's problem with the "dance". And remember, the Zorba scene was two men as well. In some areas of Scottish settlers in this country,  the "fiddle" and thus fiddle music was outlawed by the church. People were forbidden to have a fiddle. Strategically, one would often be turned over for destruction, another hidden in the attic. 
The passion of the dance - sexual or otherwise, was seen to be the entryway for the devil, sin, it seems.
