A cheeky boat captain played the Titanic song while navigating rough seas with tourists.

Footage shows the ferry being rocked by currents while Celine Dion's 'My Heart Will Go On' played on loudspeaker in Preah Sihanouk, Cambodia, on January 21.

Amused Australian holidaymakers held onto their seats and poles while jamming with the song.

Aussie Ella Depledge said: 'The captain started playing the Titanic theme tune when it was very rocky. We were more than a little nervous.'

The Titanic was a British passenger liner that sank on April 15, 1912, after hitting an iceberg during its maiden voyage from Southampton, England, to New York City.

It was depicted into an an epic romance and disaster film directed by James Cameron. It stars Leonardo DiCaprio as Jack Dawson and Kate Winslet as Rose DeWitt Bukater, two fictional characters from different social classes who fall in love aboard the RMS Titanic.
