There's one that's supposedly the retail version, but it's just the same thing looped in some parts and without the scratch and sniff.
It was supposed to be on the soundtrack for a paintball PS2 game, but we never found out what happened there.
In any case, Lethal just posted a Myspace blog not too long ago that he's going to put his solo album out on his own label pretty soon, his old label was what kept pushing it back, so I'd be keeping an eye out for that. Hopefully it's out around the same time the new LP album is.
