You remember when Ewan used to sing Tam Linn, Jim - about a protean monster that changed shape....that's folk music.

You and I may not like all the changes - but things change.

You admit literacy has changed things. But oh so many things. Ease of access to good quality instruments. technology. ease of access to foreign influence, ease of travel, social mobility.....

There is something intangible, undefinable and worthwhile. It sprang from the folk clubs of the fifties and sixties. so many of us call it folk.
I don't why it causes you such anger.
