I did a tiny bit of Google digging: Cassetteboy is a British fellow (fellows?) who has been around for nearly a decade, starting out with “cut and paste” edits of actual physical cassette tapes on an editing deck. He actually only started working with video a couple of years ago.

Check out his other work on the website I’ve linked to, or on his Youtube channel. I particularly liked his edit of the British “The Apprentice”: Alan Sugar is the “Trump” of the British version of the show.
