This song by one of my favourite Australian bands plays on a perhaps slightly unfair myth about the ANZAC leadership, but still suits the day well, and is one of the better efforts in a field that often turns to the mawkish:
ANZAC day isn't, and shouldn't ever be about glorifying war or nationalism. It's a day for rememberance and acknowledgement, of what others had to go through (rightly or wrongly) in our name, and those who fell. And as an army Brigadier eloquently quoted at this morning's Lower Hutt ceremony, the bonds of mateship. Soldiers don't often fight for the higher ideals of national policy, which are close to irrelevant on the battlefield. They most often fight for those alongside them.
NB: The Christmas Truce referred to in the lyrics was a real thing that occured in 1914.
