Watch Nearer My God to Thee
Nearer, My God, To Thee was said to have been Wallace Hartley's (Titanic's band leader) favourite hymn.
Some survivors of the sinking remember the Titanic's band playing this tune as the ship sank.
Others recall the tune played as being Songe D'Automne or Autumn, a popular song of the time.
It is unlikely that we shall ever know for certain.
