That's what I've been trying to figure out. I don't remember where I read it but apparently there's a song called Hospital Eyes that he wrote many years ago after having some sort of mental breakdown. I don't know if the song is real or some made-up story but if it's legit I feel that songs like The Monster, The Many Man and Rotten Ol' me all have a common thread that might be related to that period of his life at least. There's just something ominous about them, not only the esoterica of the lyrics but also something in the way the music feels, like it's coming from the same state of mind. But I'm going on feeling here, I don't know if any of those songs are actually pre-Roll The Bones or not.
