Thanks for the comments,y'all. There's no sheet music as far as I'm aware. I sat down and wrote out a chord sheet about 10 minutes before I started recording haha! I've been doing this a long time and it's not a very hard song. It does have one strange chord progression that I had to think about a couple of times before I figured it out, but otherwise it's pretty easy. I also ran through the melody a couple of times on the harmonica. It was fun. Maybe sometime I'll do a proper job of it and make a recording without annoying mess-ups that can actually be used as the outro music.
