Mickey Mouse Whistle

My middle school band is going to Disney next week, and so I arranged the Mickey Mouse Whistle to celebrate that. While finding some music (because I gave up trying to learn it by ear) that I could use to help me figure it out, I came across the original song. (LINK: https://www.youtube.com/watch?v=A1p-NkZ__Bg ) Apparently it's about someone named Bill who tried to break what I think is a speed record, and his boat exploded. Here's a link to what I used to help me arrange this: https://www.youtube.com/watch?v=IhAQl2W6tmE
