This is all very fascinating, and just shows how little I know about the connotations of the song. Funnily enough, I went to Edinburgh Uni, and watched quite a few Rangers/Celtic matches. (During the late 1960's) I never heard this song, because it hadn't yet been composed! You're quite right that keeping the 'English are nasty' theme going detracts from today's greedy enemies in the camp. And I concede that any song which stirs inappropriate sentiments is best not performed in a folk club setting. I have to add that, as a student in Edinburgh, I totally adored Wild Rover and all the other old chestnuts of folk songs, and we bellowed them out at every opportunity! I'd absolutely love to hear them again myself, but I suppose the groans would drown out the singing!
