I've watched this a bunch since you posted — thanks for giving this video the forum (Disputations) it deserves.
Additionally, is this a cover or did they need to secure Ghostbuster song rights? (Asking for a friend.) Finally, a nice way to watch is slightly obscured; i.e. writing this comment, only seeing the lower half of the video.
It definitely sounds like a cover version - I wonder if it has anything to do with the fact that Huey Lewis successfully sued Ray Parker Jr for plagiarism.
Yes.
