I saw what you did there...
I can tell that this was meant to be a joke.
Fortunately, I know a band who did the same thing, wich is to put the main theme at a more than anoying pitch and akward instruments to show that conformism applies to music too, and whoever strays from that path is shuned.
Unfortunately for them, it worked too well, and the band died, just like this song. I can see that, as opposite to what people think, you're somewhat talented in improvisation, and minus a few bad notes here and there, it's really not that bad.
Unfortunately, it's a cover, so I can't really give credit, and since it's MIDI, I can't say anything about your intonation.
Anyways, good job on whatever you did, including making my ears bleed!
Cheers,
