Update on an Idea for a Musical

Back to the doldrums again. Night time. Our dead ship is lost at sea, with no wind, food or freshwater. Only rum. Barrels and barrels of rum. The poor souls upon the (insert insightful name of ship here) hoped to fight in the American Revolution, but went wayward when the captain sold them out to the enemy. They have no idea how the war has gone, nor have they seen any action. Now all aboard are doomed.
But you can't tell it by looking at them. They are as cheery as ever, and the whole play opens with cheery song and dance. The crew has been sleeping under the sails on the deck all day to escape the sun, and wake at dusk to enjoy the cool night air. They know they're screwed, but they can't help but entertain themselves. When they decide the end is unavoidable, they crack open the rum and begin to drink themselves to death.
They tell their stories and share their talents together in a drunken amateur night, organized by a midshipman, Maximillian Griffin, who's only goal is to keep moral high among the few crew members left. Secretly, he stays sober, keeping up hope that they might be rescued.
Inspite of all the insane cheeryness that floats among our crew, a deep bitter hatred is brewing. Things could get out of hand at any moment. As the action progresses, the men (casting made without distinction of gender) become increasingly violent. Rumors of an unlucky shipmate undo many smiles on deck. Things only get worse when the crew learns the truth of their situation.
