Moore is best known for his political and social commentary which reflects a left-wing , Irish republican perspective , despite the fact that his mother was a Fine Gael county councillor and parliamentary candidate in Kildare . He supported the republican H-Block protestors with the albums '' H-Block '' in 1978 , the launch of which was raided by the police , and '' The Spirit of Freedom '' . He has also recorded songs by the hunger striker Bobby Sands , including " Back Home in Derry " which is based on Gordon Lightfoot 's song " The Wreck of the Edmund Fitzgerald " . He ceased supporting the military activities of the IRA in 1987 as a result of the Enniskillen bombing
