I know exactly what you mean CJB. Me and my family went to a local restaurant the other night (The Bengal Balti I think it was called?) and all they had was curry dishes, rice poppadoms and ice cream inside empty orange skins! Of course we were outraged at this blatant false advertising, as I wanted a beef dinner and my wife fancied a lasagne. It was a restaurant, operating in England with no English food. The sheer impertinence of it all dulled our appetites I can tell you. I won't even mention the background music!!!
I'm no big fan of the Beeb, but from memory (and without resorting to Google)I have seen on their channels in about the last 12 months -A Songwriters Circle on English Folk with Martin Simpson; An hour long documentary on Kathryn Tickell; Cambridge Folk Festival with plenty of English acts (Okay we had the annoying Zoe "I don't know nothing about Folk music me" Ball); two, count 'em, two documentaries presented by the Unthanks- one on Folk dance, and one on music and traditions and a documentary about Cecil Sharp house and how folkies of today are using its resources.
Speaking as a Romany I know a bit about being on the receiving end of racism. Trust me when I tell you that this isn't it :)
