Keith A. might be thinking of Miccas' "Thiepval" ( first line:
'It is all Hallows eve on the Lowlands of Flanders') which has two tunes - Miccas' own and the one that Linda Kelly created at his request. I can post the words if required (if tasked to remember them!)
It's a 'tale in reverse', absolutely wonderful and I remember the first time Linda and I were asked to sing it - at the Yorkshire gathering 2 or 3 years ago.

The words of 'Petals of a Poppy' , 'the Reaper' and 'Scarecrow' all made me think once again of the sacrifices made.
Thoughtful words - Brave people.
Remember them.

P.S.Does anyone recognise this chorus/refrain?

'Old, old soldiers only fade away,
Old, old soldiers never die.
It is we who forget what they've done for us,
and we never say thank you, or goodbye.'

I remember hearing an Army Captain, Gerry Webb, singing in NI, 1981 - but can't recall more words.
Thanks,
Hazel.
