The article says that it's available now at the Invisible Records web store but I wasn't able to find it anywhere on there, so it might be showing up soon. In the meantime (and this is how sheltered I was as a child), you can check out the original version of the song that I've never heard before at Pigface's MySpace page.
Thanks to Nicole for the head's up!
*Edit* Tom VX is better at the internet than I am. Travel here to check out the remix album. Thanks!
