Document 15: Famine Song: The Famine Song is a song sung by some Ulster loyalists in Northern Ireland and Scotland and is normally directed at Catholics and, in Scotland, Irish people, those of Irish descent or those with perceived affiliations to Ireland. It is also sung by fans of Scottish football club Rangers due to rival Celtic's Irish roots. Set to the tune of "The John B. Sails" popularised by Carl Sandburg, the lyrics of the song make reference to the 1840s' Great Famine of Ireland. The song is often heard at loyalist marches in Northern Ireland despite many loyalists being descended from refugees fleeing famine in Scotland, and the Great Famine being an event that impacted the whole of Ireland. The Famine Song has received criticism due to the racist and sectarian nature of its lyrics and, in some cases, those singing it have received criminal convictions.
