"crusade to convert the world to their new found religion?"

Oh poo to you! I've no interest in converting people or telling them how 'great' it is. It's as square as fuck of course, and definitely no chance of a shag going for anyone under retirement age either, and of course that's all fine(ish). But traditional song does exist in an hermetically sealed bubble, mostly populated by people as old or older than my parents. And utterly isolated from people like me, unless we happen to fall over it. All I think is that more people should have the opportunity to decide for themselves. Otherwise, I'm quite happy to disagree with you on the matter...
