Surely the only spelling is Eton as that is the name of the school, and village?
The Kippling poem is called Screw Guns and is a good chorus song
My favourite verse is
A wheel on the horns of the morning,
A wheel on the edge of the pit,
A drop into nothing beneath you,
As far as a bugger can spit,
And the sweat running out of your shirt sleeves,
The sun off the snow in your face,
And half of the lads on the drag ropes,
To keep the old gun in her place.

Stand easy my long eared old darlings
Keith.
