Dave, Roddy was written around 1902.

Greg, that was not me but Martin Ryan, surely with Jim our most knowledgeable authority on Irish song.

Al, Rising of the Moon is about the 1798 rising, but contains no anti British sentiments or anything for or against British rule, even though by the time it was written the famine had happened as well!

Rag, I think you are agreeing with me, and contradicting Al, that there are few anti-British songs pre 20th Century.
