Love Ire & Song Lyrics

Lyric discussion by Occupied By Tim 

Cover art for Love Ire & Song lyrics by Frank Turner

Does anyone know what Frank is really talking about in this song? It's great that we have these little interpretations of verses, but I'm just wondering what the whole of the song means. I get that it's about reliving the past, and being successful in that, but what exactly does "fighting and winning" mean?
