Eric Bogle also wrote a song for Dunblane "One Small Star": it does not specifically mention the disaster, and remains a song that may give hope and comfort to those who have lost someone, whether in tragic circumstances or by natural causes. (It was recently mentioned in another thread for someone who had lost his father.)
I don't find that excruciating.

There were a whole bunch of songs writen about the Napoli grounding on the Devon coast in January 2007, but there was an element of comedy there in how the wreckers moved in and the booty they took. I don't think there's much comedy about this oil eruption.
