Jack Campin, the practice of Irish people 'refusing' to acknowledge the nationality of English composers is non-existent. Nobody has ever refused to acknowledge the nationality of Cyril Tawney, Ewan MacColl, Lennon and McCartney or anyone else.

Omission is not the same thing as refusal. Irish people are not the only nationality who omit the composer's nationality when crediting their name. English people do it too. It is normal practice. Why are you singling out the Irish?
