I first heard this song on Dr. Demento sometime in the 80s, but I had no idea there was a video. It is awesome -- especially the last 35 seconds. It aired before VCRs were available, so someone recorded this by pointing a camera at a TV screen. You may need to crank up the volume on your machine, but it is so worth it.
I (or at least the YouTube poster) give you Leonard Nimoy and "The Ballad of Bilbo Baggins."
