By naming it purely "English" they are creating a barrier to progress. Even though they are hosting a variety of international style events.
Many will see "English" in the title and proceed no further if they are looking for another genre.
Re-naming may attract a greater following thereby increasing membership and of course available funding.
This might alleviate the amount of begging from the "Heritage Lottery Fund"
Of the many thousands of people who buy lottery tickets few will benefit from the grant I suppose.
Don't get me wrong, I am not against preserving culture and heritage.
I just don't think any society dedicated to doing so needs any misleading or off putting barriers to attracting interest.
I have been playing and singing both traditional and contemporary music for some 40 years. In all that time I have not seen one advert for the EFDSS nor been approached to see if I wanted to join.
Which seems to suggest they might need a better marketing team. If in fact they have one.
