Well, I found this:

ALL FOR THE WANT OF NAIL

If it's climbing you'll go, there's a tale you should know
That will make you both quiver and quail
Of a hole in your toe where a clinker should go
And it's all for the want of a nail …

You're a thousand feet high and you're nearing the sky
You can't get a grip on the shale.
Only ten feet away, there's a perfect belay
And it's all for the want of a nail …

There's scarcely a grip for a small finger tip,
And a thousand foot if you fail.
There's a pumping machine where your heart should have been
And it's all for the want of a nail …

Well, the good Lord looked down, and he laughed like a clown,
"There will soon be a ruc-sac for sale !
If these boots don't deceive us, this guy's going to leave us …
And it's all for the want of a nail …"

They scraped his remains off the sharp rocks below
And gathered them up in a pail.
And the toast that they drank to the body that stank,
Was ' it's all for the want of a nail …'

They buried him high, where the cliffs meet the sky
And round him-set a white wooden rail.
And if you examine it, there you will find,
It was all for the want of a nail …

Now this is the end of my sad little song,
This is the end of my tale.
Don't ever go with a hole in your toe,
Use VIBRAMS …. They never will fail !
