Fun little fact: I played this to my friend a few months ago, and I improvised this ending all by myself! And that's how I came to play this song exactly like this.
Apparently this didn't upload to OnlineSequencer, but luckily, I had it saved as a MIDI file in Synthesia. All I needed to do was painstakingly restore the volume of the notes back to default...
