I can't help you with the music or chords but the lyrics are at least pretty close to this:

"TWO LITTLE BOYS" sung by Rolf Harris

Two little boys had two little toys,
Each had a wooden horse.
Gaily they played each summer day,
Warriors both, of course.
One little chap then had a mishap
And broke off his horse's head.
He cried for his toy then cried for joy
As his young playmate said,

"Did you think I would leave you crying
When there's room on my horse for two?
Climb up here, Joe. We'll soon be flying.
I can go just as fast with two.
When we grow up, we'll both be soldiers,
And our horses will not be toys.
I wonder if we'll remember
When we were two little boys."

Long years passed. War came so fast.
Bravely they marched away.
Cannon roared loud, and in the mad crowd,
Wounded and dying, Joe lay.
Up went a shout and a horse dashed out,
Out from the ranks so blue,
And galloped away to where Joe lay,
And then came a voice Joe knew:

Did you think I would leave you dying
When there's room on my horse for two?
Climb up here, Joe. We'll soon be flying.
I can go just as fast with two.
Do you know, Joe, I'm all a-tremble?
Perhaps it's the battle noise.
But I think it's that I remember
When we were two little boys.
