On my munzly blog, I've posted a great song from a great Filker. So if you know what that is all about or recognise such characters as Cthulhu, Mummies, Werewolves, Minions, Hunchbacks (of Notre Dame), Cylons, Daleks, Zombies, Dark Lords, Vampires or Shoggoths, then this is for you.

Good idea to publicize it further - great song!
I first came across filk a few years ago and it surprises me that it isn't more popular.
