All traditions are regularly changed (broken - by mustrads terms of reference) by cultural and political influences, such as scottish and english music arriving in donegal. If someone had policed donegal fidil music in the 17th century to ban those influences and keep that tradition 'pure' we wouldn't have those tunes today. If some are ignorant about mustrads policies then perhaps that's due to a slight holier-than-thou attidude which does not encourage one to explore further.
