Caribbean Nights

Picture it, its a night out in the Caribbean, and you set off to sea. You start to go and everything is going well and everyone is happy (measures 1- beat 2 of measure 5), and then everything starts to fall apart (measures beat 3 of measure 5-8), then the crew starts to think of a plan, and it works (measures 10-18). (Measures 19-24), everyone shows relief and doesnt have to worry about a thing.
