This song is about the warped education McFadden received at a Christian brothers school in Dublin. In the November 26, 2004 edition of the London Daily Mail, McFadden said: "Irish Son is me looking back on a Catholic upbringing. I still have faith in God, but I've lost my faith in the Catholic Church. There are some great priests in Ireland, but there are some bad apples, too."
This was co-written by Robbie Williams' former songwriting partner Guy Chambers.
The video caused controversy as it showed a Christian Brothers school in Sutton, which was inadvertently named as a hotbed of brutality.
