There are several; there is a hymn called the Canticle of the Sun, which is the one where he goes on about brother sun and sister moon (or burning sun and silver moon for the hymnbooks) which is 'All creatures of our God and King'.

Then there is the Make me a channel of your peace, which can be found in most modern hymn books like Mission Praise, Celebration Hymnal or Songs and Hymns of Fellowship.

It was paraphrased and set to music in the 70's and quite quickly gained popularity.

Then there is another version of the canticle of the Sun which is partly in italian - Laudate te, o mi Signore. That is in Celebration Hymnal as well.

Most of those books should be available both sides of the pond but you may have difficulty with Mission Praise, as it is getting a bit old now..... not unlike myself!

If you have trouble, I can do the lyrics but not the tune. If you have a private address I can scan it and send it to you. Let me know through Personnal Messages if you want.
