The Message of the song is reactionary, and that awful verse

And I courted Peggy Dignan, as pretty as you please,
A rogue and child of Mary, from the rebel liberties,
I lost her to a student chap, with skin as black as coal,
When he took her off to Birmingham, she took away my soul.

I suppose it would have been alright would it if the student chap was a fine upstanding Offaly man, like Biffo big ignorant faeller from offaly its sentimental clap trap with racist undertones and kind of student dislike
