Dexy’s Midnight Runners vs. Public Enemy
I’m pretty sure this is/was Freelance Hellraiser’s work, but I can’t recall - it was 2002, and I was but a young’un.
Still, throughout the whole history of the bootleg/mashup, and into Girltalk’s new era, I still think this is the best of the bunch - mostly because, at barely half a minute, it knows when the joke is up.
