It is song lyrics from band aid '84, hardly offensive to anyone without a stick up their ass, every xmas they drag it out and respam the charts with it, and whadda' ya know? It hit #1 again this year....
1984 is slightly before my time and I haven't heard of that song until today. so I apologise as I completely had no clue what it was in reference to.
My bad for the misinterpretation!
