From my experience of Ceroc in the Thames Valley - I'd go along with what you are saying about the South East but that's not how is throughout the rest of the country, particularly the North and Scotland. However, saying that, I was introduced to Ceroc via American Square Dance and Contra Dance. I think its a function of London being a bigger population centre and people being able to get the dancing of their choice. In Scotland and the North unless you want to travel miles you take what you can get, so if people can't get to AT they do WCS, Salsa or Ceroc. I'm certainly not saying AT is dependent on MJ, what I am saying is that as an MJ dancer I know people through MJ who do AT, WCS, Lindy or Salsa as well as MJ, which is what you do when there is nothing else. Ceroc is the sort of connection point where the dancers from every other dance form eventually meet up. As for the teaching system. It depends on the size of the class. In Scotland the Ceroc model is used where there are large class sizes - in WCS, Lindy and Salsa, but less so in AT (from what I've seen). If the class gets about 20, its the Ceroc model. In Ballroom I've had experience of some very good teachers - but they teach routines in a strict way that would make a Ceroc teacher scream. The routines are taught in such detail its almost impossible to get any actual sensation that you are leading. It's more like synchronised movement than the kind of leading you expect in AT, Swing or MJ. Swing - Lindy and WCS - are at a similar level of popularity to AT in Scotland. In terms of numbers I would guess its roughly 35% Salsa 35% MJ 15% AT 15% Swing. I'm just back from Southport and meeting Brent and Kellese Key - briefly. I think I'll start it as a new thread.
