I was on Deviant ART earlier, and one came to my attention, by someone I know, and I think it's pretty kick-ass. Basically he's done his own lyrics to Still Alive and then recorded them: here's the links needed.
"They'll tear you apart, bone by bone... ...and build with you a human throne. Their buck- toothed king will sit upon What once was you, but now is gone. This key unlocks the gates of Hell. Steady traveler, use it well." - Grim Fandango - Poem of the Flaming Demon Beavers
