Once again I sigh at opening a can of worms here.
I don't think any sane person could honestly laugh at the hardship of those who lay dead, for such a pointless cause, But is, as mentioned above by martin ryan, more aimed at the people who basically destroy a fine song, because, the odd time this is performed, what does go through the audiences mind is, "God yeah i can just picture that idiot dribbling out that song..." NOT ha ha to the poor c**t who got killed.

In my searches I have found a few other parodys of this song, which i would never look at twice, as i myself feel them to be a bit close to the bone. Look yourself if you wish, they are easy enough to find. I do appreciate the forum here as a open ground for one to express opinions, as it should be, but Julie, please note, the laugh in this version is directed at those who ruin the song, not those who inspired it.
