This is a pretty scuffed edit but it gives you an idea of what the song could sound like with vocals at the correct pitch.
I chopped up the song as it is and pitched it up and down to fit their normal voices without losing as much quality as possible. Chucked them all back at the original tempo too.
The instrumental differs in pitch but at least you get to hear what the vocals would sound like if it was their normal voices.
