I believe there were Nazis in death camps who used to like having the music of Beethoven and Schubert as background music to the killing.

A tune isn't responsible for the disgusting people who choose to play it while they are at btheir work of murder. But it can become inescapably associated with such events.

Has anyone ever written set of words to Garryowen about Custer's massacres? It could be a way of rehabilitating the tune maybe.
