The Titanic song

This is a popular children's song about the sinking of the Titanic. The subject of the song is very sad, but it sounds like a happy song.

Oh, they built the ship Titanic to sail the ocean blue,
And they thought they had a ship that the water couldn't go through,
It was on its maiden trip that an iceberg hit the ship,
It was sad when the great ship went down.

Chorus
Oh, it was sad, so sad; it was sad, so sad;
It was sad when the great ship went down, to the bottom of the ...
Husbands and wives, little children lost their lives,
It was sad when the great ship went down.
