Thanks for all of the replies. I have only started new threads about six times, on various forums and this is the only one I have had a decent response to. I think SCD must be getting more popular. Just as a matter of interest I did ballroom dancing as a boy for over 10 years. It was almosty totally dominated and controlled by us Brits at that time. There were only four recognised "modern" (i.e ballroom) dances (W,F,T and Q) but there were 5 "latin" dances (R, S, C, T and J) although the Jive was a bit of a newcomer. Competitions were usually ballroom or latin but then it was decided to also have "all round" competitions and these were 8 or 9 dances, usually the latter. Of course, that gave an advantage to the latin specialists.
Then the whole thing became more international and the Germans, Scandinavians and Japanese took it up, along with a few from the Commonwealth and the USA. The Germans in particular pressurised to have the VW included as a "modern" dance even though it is different in that it is more like Old Time dancing, where everyone does the same steps at the same time. They used the reason that it would balance up the all round competitions and make them 10 dances. Of course, the fact that they were better at the VW than everyone else had nothing to do with it. Anyway, internationally, this had the effect of reinforcing the Jive as a "latin" dance. Hope this is of interest to some of you.
