name='ShirlGirl']No it's not like that - it's not "Titanic - the Musical"! (Heaven forbid that there should be one!)
The story is about Molly Brown and in the movie she is a saloon dancer. Hence the musical side of it. In reality - and in the movie - after the Titanic sank and she was in a lifeboat, she tried to keep everyone's spirits up by encouraging them and leading them into a sing-along.
P.S. We might not still be talking about the Natasha Richardson tragedy but I'm sure it's not "forgotten", not at all.
