Usually these diagnoses are all wrong, but most of these seem to be correct.
Jim Gordon, Derek and the Dominoes: schizophrenia. Never heard of him, but the dx sounds right.
Roky Erikson, 13th Floor Elevators: schizophrenia. Definitely a correct dx, and I have read some “interviews” of him that make that clear.
Gary Glitter: pedophilia/hebephilia. Something along those lines. He likes way too young girls way too much.
Peter Green, Fleetwood Mac: hallucinogen abuse, schizophrenia. However, he is still playing a lot now and has made a near complete recovery, which makes me question the dx.
Jaco Pastorius, Weather Report: alcohol abuse, bipolar disorder. Beaten to death in a fight with a bouncer, ruled justifiable homicide.
Bud Powell, jazz pianist: unknown, alcohol abuse, other unknown issues. Schizophrenia dx seems wrong. Dead of cirrhosis at age 41. Got beaten badly over the head by cops and his mental stuff started right then.
Per Yngve Ohlin, Mayhem: Depression. Suicide in 1991. Slit both wrists, then flew his face off with a shotgun. There is a bootleg out there with a photo of his dead body on it. Do not look it up as it is very gross. His brains are everywhere.
Sid Vicious, Sex Pistols: Heroin addiction, other unknown issues. Would be interesting to see what sort of a dx you might give this guy. Depression? Antisocial personality disorder? Who knows. Girlfriend Nancy Spungen died in their room at the Chelsea Hotel of a knife wound. Sid might have done it, but maybe he didn’t. No one really knows. He did confess. She is said to have had a diagnosis of paranoid schizophrenia, but that seems all wrong. Bipolar disorder and Borderline Personality Disorder are the new updated dx’s and they seem a lot better. Why not throw in Antisocial Personality Disorder while we are at it. She is a perfect candidate.
Skip Spence, Moby Grape: Hallucinogen abuse, schizophrenia. Dead in 1999. Last time someone tracked him down, he was living under a freeway overpass in San Diego. There are some recent photos of him, and he didn’t look very good.
Syd Barrett, Pink Floyd: Hallucinogen abuse, schizophrenia. Excellent dx, 100% correct. Died at his mother’s house a few years back.
G. G. Allin: Drug abuse. I haven’t the faintest idea what dx to give this nutcase, but if you say he was normal and don’t dx him, the word normal then loses all possible meaning. Sort of a Sid Vicious type except he was a lot worse. Antisocial personality disorder seems about right, and God knows what else. He didn’t appear to be psychotic in my opinion, but you don’t have to be psychotic to be seriously whacked in the head.
