The English by and large have always derided their customs as quaint, except at certain times of the year when they are accepted. Traditional folk has largely and long been under the radar and most of us are happy with that. It is part of the attraction! Those who aspire to be household names, having started off in folk circles, have usually done it under another genre guise, pop/rock music, comedy, at least in this country.
'Strong and resilient?' Of course. We may be few but we are die-hards who love the music. The word 'niche' springs to mind.
