Query: A fantastic resource for songs about our living planet.

Almost 400 pages full of great songs complete with sheet music and guitar chords. There are also short biographies of some of the composers. This appears to be the most complete book of its kind!The songs are divided into musical categories such as "Earthly Elements", "Prayers and Praise", "Circles and Cycles", "I and Thou", and "Changing".A wonderful uplifting musical source book!
