To Richard and Phil:

Who, me? Thanks for noticing.

why not practise/perform/ENTERTAIN WITH our own

Because they're not "our own" in any meaningful sense, as I explained at some length in an earlier comment. To paraphrase myself slightly, there are still a few people out there - even in England - for whom the words "our music" mean something real and definite, but I'm not one of them and neither are you.

I'm not into just English traditional music

So you go into a forum full of people who care deeply about traditional music but mostly don't care particularly about whether it's got the English label on it - and you tell us that what we should care about it not whether it's traditional but whether it's English. And when we disagree, you tell us again.

No accounting for tastes, I suppose.
