Amazing, Did anyone know? It is called Sarnia Cherie. Check YouTube and listen to it. I liked it, anyway. Stefan.
I have seen a couple of documentaries on Guernsey, not sure the anthem was part of it. One is called "Hitler's England, featuring John Nettles, by the German producer Alexander Berkel. Stefan.
The wiki page does have some details - Sarnia Cherie - Wikipedia Including the mention that it is used as the unofficial anthem. Possibly the official national anthem is... God Save the Queen - Wikipedia Or the Duke of Normandy ;-) Duke of Normandy - Wikipedia In the Channel Islands, the British monarch is known as the "Duke of Normandy", notwithstanding the fact that the current monarch, Queen Elizabeth II, is a woman. The Channel Islands are the last remaining part of the former Duchy of Normandy to remain under the rule of the British monarch.
