M.Ted, You come over to me as an arrogant sod.

Believe it or not, there are a great many fine Jazz musicians on this side of the pond. There are also people on this side of the pond who are very knowledgeable about Jazz. To use your expression, they have studied and understand the stuff.

We are more than happy to acknowledge the American origins of Jazz, but I think you really ought to appreciate that good Jazz is not confined to the USA and this has been the case for many years now.

I think it is fair to say that we are unlikely to find real Jazz experts on a folk music site - from either side of the pond.
