The theme song from the film Titanic is said to have been playing in one of Costa Concordia's restaurants as the cruise ship began to list.
Yannic Sgaga and his brother Kevin told Swiss paper La Tribune de Geneve Celine Dion's My Heart Will Go On from the hit 1997 film was playing when the accident happened off the Tuscan coast on Friday.
"Images from the film Titanic are more realistic than one might imagine. They kept coming into my head," Yannic Sgaga said.
The claim is one of several comparisons to the 1912 Titanic disaster - and the film - made by people aboard the Costa Concordia, which hit rocks near the Italian island of Giglo on Saturday.
It has also been revealed one of the survivors aboard the cruise ship is the grand-daughter of a woman who survived the Titanic disaster.
