The villagers said Prophet Fred persuaded them to turn to Christianity by foreseeing a number of natural events.

He predicted that a lake at the foot of Mt Yasur would be swept into the sea. Five months later, in early 2000, the lake burst its banks and drained into the sea. Now all that remains is a black volcanic plain covered in grass where horsemen ride and cattle graze.

On Feb 15 each year villagers celebrate John Frum Day by marching in GI fatigues, complete with badges of rank and khaki forage caps.

The men paint red crosses on their backs - a legacy of the US army medics who impressed them six decades ago with free treatment.

Drawing the shape of a US flag in the volcanic sand with his finger, Chief Isaac said: "John predicted the Americans will help us. He will make the whites bring us cars, wharves, airports, everything. John will bring a better life."
