Woody Guthrie's "Plane Wreck at Gatos" says it all on this subject. It is just dreadful. I don't see, by the way, what is gained by suggesting that eating cockles is an upper middle class activity. A wander along Morecambe front in the summer will soon show you who is eating jars of cockles. I am sure the Morecambe tourist indutry would love a slightly posher clientele, but they don't get it.
