Â Â Â Â 37 have been published by or with the blessing of the RSCDS
Â Â Â Â Â Â and, of this 37, 12 are traditional dances while 25 are modern dances.
A mere 13 modern dances not published by the RSCDS are in the top 50.
This does lead one to the conclusion that dances published by or with the blessing of the RSCDS have a far greater chance of occurring on a social dance programme. (This is probably due to the fact that teachers and programme devisers will have easier access to RSCDS dances than to other dances.)
Also, it is interesting to note that modern RSCDS dances are more popular than traditional RSCDS dances and that, overall, modern dances are more popular than traditional dances.
I suspect that the majority of the 347 that have occurred only once will be modern dances and most are likely to be 'local' dances devised for a local event or a local 'celebrity'.
