Independent Irish label: The Andersonstown Civil Resistance Committee issued a single by Barley Corn, 'The Men Behind The Wire' (CRC-71), on the C.R.C. label in 1971; it can be filed under 'Irish Republican Folk'.  There seems to have been just the one issue on the label, though the existence of two slightly different kinds of label - one without full stops, one with - suggests that there were two pressings. Thanks to Robert Lyons For The Info.
