While I acknowledge the humor to a certain extent, I have to say that our knowledge of events 1000 years ago is more complete than the video suggests. Yes, the average person on the streets may think that Charlemagne and Emperor Constantine lived at the same time, but the historians would never make that mistake. And while music creates it's own issues given the possibilities of losing audio evidence, thus giving rise to the performance at the end of the video, academics are also careful not to make claims that don't have clear evidence. Joining Scottie Pippin to the Beatles, and the Beatles playing in the Super Bowl, would take some massive misunderstandings of our current culture, suggesting that a major cataclysm wiped out practically all of our cultural products, like recordings, posters, books, and Larry King. And that doesn't match with our experience of the last 1000 years. After all, Larry King is still alive.
