This is a song in praise of creation and a caution for our misuse of God’s earth. It is another of the Shirley Murray texts in Alleluia Aotearoa.
The words are at Hope Publishing. Both they and AA set it to NEW FERN by frequent collaborator Colin Gibson. The odd thing is that the verses have uplifting chorus type music and the refrain changes key and sounds more downbeat. The last refrain has different lyrics and leads into the fifth verse, which ends the song with no final chorus. So maybe there are five “refrains” and a repeated verse.
My BIAB uses made up chords based on the sheet music.
