Oh go on. Morris is a genuine and interesting cultural phenomenon.

Yes, I agree. (I think we agree on more than you realise.)

Traditional music is not easy music. To do an unaccompanied song well is probably the toughest call of all.

I'll take that as a compliment! But I don't agree that learning a couple of verses, and struggling through till you get to the chorus where everyone joins in, is harder than bashing out three chords. People who really can't sing are few and far between - and if everyone's expected to take a turn, over time everyone will get lots of practice.
