here is my attempt...
Our Islands, which art in Water
Shallow be thy shores.
Thy Vikings come
Shetlands be done
In Unst as it is on Mainland
Make our fair way to western isles
And forgive us our sea journeys
As we forgive them that build bridges between us
And lead us not into renaming
But deliver us from Eilean a' Cheò.
For thine is the Rassay, the Islay and the Barra
With Mull and with Jura
