Ditto the Greek/Macedonian dances - they too are circle ones, often passing the "led" to the next dancer at the end of each tune and so on. No line dances anywhere in the Balkans or the Med, that I am aware of.

The way I see it, line dancing is about conforming (I think AllanC said that). They all must move together as if pulled by a single string. And that is all - this is the target, no more than that. Nothing about grace of step or movement, nothing about expressing feeling with movement.

While in Mediterranean, and Jewish, and Balkan dances, uniformity of steps is simply meant to provide a backcloth for the intricate extra moves of the leading and trailing dancers, and expression of feeling and mood plays a very important part.
