We 'mudcatters' are a group of people from around the world that enjoy communicating with each other on music related subjects (of which I'm delighted to learn are many and interesting). Perhaps we could be a forum which could clarify "what is what" to some extent with our collective wisdom. I like the idea of setting up categories of "celtic" music and making lists of songs for each category. That way when we are playing before an audience who may question our selection of "Irish" songs we can refer them to the "Mudcat Standard of Folk Music." Just a thought...
