My comment about Scots and Irish tending to be more narrowly focussed on their own music was simply based on my observations of playing in many sessions throughout the UK over many years. On the whole, I have found that musicians in Scottish and Irish sessions have tended to be less accepting of tunes from other cultures than have musicians in "English" sessions.

Of course, every session is different and not all are like that. I certainly wouldn't claim that all Scots and Irish musicians are like that. But I think they do tend to be narrowly focussed on their own traditions and this is sometimes to the exclusion of other influences. WAV will think this a good thing. I disagree.
