mg: Ah - I see what you mean now. That's not something that happens to me, but I know what you're talking about.
Re 'Star of the County Down' - this is from the Jersey Jaques 'sleeve notes':
"For The Trial song I've made a new tune that runs over a version of the melody Kingsfold, which was collected by Ralph Vaughn Williams in Dorset, though the earliest written reference is the Scottish Gilderoy c1726. It crops up under many lyrics (including hymns), the best known being the Irish Star of The County Down (words by Cathal McGarvey 1866-1927). The Star's happy, 'boy-meets-girl' lyrics and arrangement would not have suggested themselves for the trial scene, but the 'transportation' variant Van Diemens Land - which uses the melody in a darker mood - was ideal. Van Diemens Land comes in many forms (often with other melodies), but most are related to Henry The Poacher, The Lincolnshire Poacher and other songs about transportation. (U2 recorded a completely different song of the same name)."
So perhaps you see what I mean, too.
