An Open Letter From a Diamond

Can someone help? I remember this spoken, to music, back in the
70's I think. I may have even had a poster with this, aprox 30-35
yrs ago. 

It is called Desiderata, by Max Ehrmann, 1927. Check this website:
http://marilee.us/desiderata.html The website also has links at the
end that connect to translations in many languages.

I had a framed copy in my office when I was a school principal. Many
times it was just what I needed when overcome by the stress of that
job.
