What's Going On With Metallica And Their Enter Sandman?

What the heck is going on with Metallica and their song Enter Sandmen? Just the other day we had the cover done by Robert Fripp from King Crimson (along with his lovely wife click here if you didn't see it) Now someone has taken Enter Sandman and matched it up with Huey Lewis and the News' Hip To Be Square. Those two songs have been out in the public's ears for years and we are pretty sure no one ever thought they would match up, and yet here we are. Could you imagine if this actually happened in real life? Huey Lewis opening for Metallica? This mashup live? Stranger things have happend!
