No sian, I don't really define Celts as Irish and Scottish - but it is so much easier to use one word that has become a catch all phrase for the genre. In truth we will be using a song written by an imigrant from Wales in the show ... we are including songs and stories from Anglo Irish (which I presume may not be Celt) but there is no need to go into that much definition in a quick discussion where the commonly accepted genre name would work OK.

There is much immigrant history in the development of US culture and music. It is a fascinating story ...
