This was an entry from the Crumplbangers challenge, Artist Name Puns, back in March 2022. I didn't have a demo channel or way to show them at the time, but I figured that with TikTok's reliance on mashup concepts, why not show them even if they're not 100% since they'll lay dust for too long.
If you ever wanted to hear John Cena rap over a John Williams piece, you're in luck.
