I am torn between my revulsion of nationalism, or worse, patriotism, being anywhere in a catholic liturgy and being glad that not every hymn is from the northern hemisphere and ill suited to Australia.
Being by the wonderful Michael Herry helps as does its setting to THAXTED by Holst – not an Australian tune but most uplifting.
Herry has the sheet music and text for free here and you can listen to it there as well. My backing in the other hand is BIAB overreaching. CWB II has a bonus descant by Richard Proulx for the last verse, which is somehow copyright to GIA.
