I don't own the song, that belongs to Junichi Masuda.
It all started when I was arranging music for a Pokémon music cover band that I want to start. Basically, I was listening to the Route 1 music and all I could envision with it was a polka. Instantly inspired, I threw up a quick mock arrangement in Logic and then recorded this muffin. Ignore the couple mistakes I made. I didn't feel like doing 15 takes.
