I just watched the Channel 4 doc. "Hunt for the Arctic ghost ship."

It tells the story of the expedition and how Erebus was found.
They searched somewhere called "ship place" in Inuit oral tradition and quickly found it using sonar.

There is film of the well preserved wreck including interior shots.

It was a hundred miles further South than had been believed.
It means they reached a part of the passage that had been charted from the West, completing the mission.

The song was played over the end credits, but a trail was put over the beginning.
