Haven't heard about him in a long time, but you might want to try to locate some recordings of Ric Masten. He wrote some lovely, meaningful songs, and performed them regularly on the UU church circuit. He was from California, as I recall, and one of his songs ("I, the Caterpillar") was recorded by Rosalie Sorrels.

Lorre Wyatt has also contributed some fine songs to the struggle for social justice, understanding, and addressing environmental concerns. His song "Somos el Barco" has been recorded by a number of singers. It wasn't finished when he recorded it for Folk-Legacy, but others have recorded the completed version. (Seeger, Jane Sapp?, etc.)
