The Colour of the Earth Lyrics

Notice that the album version they use a capo in the first fret.
When it's played live, they don't use it.
Louis was my dearest friend
Fighting in the anzac trench.
Louis ran forward from the line,
And i never saw him again.
Later in the dark
I thought i heard louis' voice
Calling for his mother, then me,
But i couldn't get to him.
He's still up on that hill.
20 years on that hill.
Nothing more than a pile of bones,
But i think of him still.
If i was asked i'd tell
The colour of the earth that day;
It was dull, and browny-red,
"the colour of blood" i'd say
