Well I don't like Irish tune books and sites (especially thesession.org) laying claim to every tune there is whether from someone else's tradition or of known composer as 'Irish trad', but they do.

Anyway, what's this conclusive proof you have that Morris is an 'English' dance? Is this the definitive answer we have all been waiting for? Do tell.

PS Richard you surely can't be serious in including The Princess Royal in your proposed ban on 'Irish' tunes being used for English dance? I think you are just hatching a plot to marginalise dance altogether . . .
