A song about the undead in Orlando

You have to hear this song "March of the Undead" about "the undead of Orlando" from The Invasion. Are they talking about the Zombie march? Their sound is like a mix of Rufus Wainright and Queen... and Orlando!

The first song that the little player on the website plays is "March of the Undead." it only plays a preview, but still, it's just cool to hear the word "Orlando" in a song.
