Dude, "Disillusioned" is already on the Rarities and Demos fan club cd. It's the "Taunting the Notorious" demo that contains a different solo section, part of which would later be used in "The Witching Hour".
"Victim or Prey" is a demo of what eventually became "Rapture or Pain" as released on the self-titled album.
Not sure what "House of Wax" is. Could be the demo track known as "Danse Macabre" which is a mix of Romeo's "Masque of the Red Death" and parts of "Rapture or Pain" as it exists on the self-titled album. Could be something else entirely though.
