I need help idenfiying the original song from this .mid file

I'm developing a megawad so I asked my uncle who used to make doom mods back in the day if he could find some midi songs and/or sprites, he sent me this midi song and a midi version of Walk by Pantera, he said he doesn't know what song this midi is supposed to be and that it's probably something from Ozzy Osbourne but for me it sounds more like something from Iron Maiden, maybe from Juda's Priest

here's the midi I'm talking about:

that midi.zip

Well, it ain't Sabbath!

Definitely has a lot of Maiden hallmarks but I don't recognize it

I can't place it but it sounds like something Stratovarius would write

This might just be the source

Wow, good job finding it. I knew it had that KoD feeling because that midi was just way too intricate and complex to be just any random sequenced composition. But as a side note, some of KoD's composition are iron maiden, heavy metal or video game music inspired, so technically not everyone was far from the truth.
