Just did a search on WW-I, Flanders Fields etc;

Here's a particularly poignant site:

Heritage of the Great War; Belated Salute

It seems that Volunteers over in France and Belgium conduct archaeological digs ahead of planned construction developments in order to preserve whatever remains might still be there.

Apparently there are a lot of them still being turned up.

In a couple of photos on this site, a pair of Buglers from the local Fire Brigade are shown playing the "Last Post" during the internment of one unknown British Soldier whose corpse, still in the remains of his uniform, was discovered by a local Farmer digging in his garden.

They say that "It happens all the time".

And the bugles STILL "Sing the Last Post and Chorus".
