The cruise line's main argument seems to be a little weak in my opinion. If someone murders someone else in the middle of the ocean, does that mean that they can't be tried because laws don't apply? I don't see how copyright would be any different, just less violent.
One of the creators of the Broadway musical "Grease," Jim Jacobs, is accusing the world's biggest cruise lines of piracy, contending that they have been staging his play and others at sea for years without permission.
Crews of actors have entertained passengers afloat hundreds, maybe thousands, of times by donning poodle skirts and leather jackets and belting out "Summer Nights," Mr. Jacobs said. But neither he nor the estate of his collaborator, Warren Casey, who died in 1988, has received royalties, he said.
