There  are many iterations of this song all over youtube.  I find this one poignant because of the juxtaposition of the military band so prominently in the foreground while the children tucked almost completely out of sight intoning the hopeful hymn – “Give us peace”.  Draw your ironic comparisons as you wish.   I’d stop at 1:45 as the rest is seems a little out of place, so don’t say you haven’t been warned. :)
