The resources below are for an arrangement of John Warner’s song, with the Alto line the same as the Bass, except for the end of each phrase. The basses of course sing an octave lower. The tenor line is identical to the melody, except for a phrase at the end of the 1st line, and a phrase in the chorus.
That key is a bit high for some choirs and singers. Below are resources for an arrangement for the Illawarra Union Singers. I’m suggesting either F for unison singing, or G for part singing. The guitar chords on the lyrics below are in the key of E, and would require a capo. Note also, the chords in the key of G on the sheet music, probably a better solution if the song is sung in G.
