I recall seeing this before, perhaps at the UMA, but I am very happy to see it again. It always makes me think "What a very cool but very strange endeavor... setting all the FM covers to In The Hall of the Mountain King!"
I just found it while snooping around YouTube. If somebody posted it at the UMA, I missed it.Somebody did a great Universal Monsters clips reel to "Mountain King" (which was posted at UMA). Wonderfully edited!
