Great to see and hear, Ted; a nice window into your life. Nice playing; you all held it down and sliced it up when necessary. The song has always been a favorite for me, not so much for lyrical content as for melody and rhythm. I think it's one of the more distinctive Hendrix tunes. But the lyrical content is really important stuff and I'd like to comment . . . Jimi did a nice job with the lyrics conveying sense of duality and ambivalence. It's interesting to note the word ambivalence was coined by the same psychologist who invented the terms autism and schizophrenia.
When this song was released in 1967, not so much was known about the cause of manic depression, now known as bipolar disorder. Some people theorize bipolar does not even exist as a single illness, but is part of the spectrum of illness from Attention Deficit Disorder (ADD) to autism and all the way to schizophrenia.
I think they're all connected and for the most part may actually be of biological cause, not so much heredity as commonly thought. More and more evidence is mounting about environmental pollutants as cause of mental illness including chemical toxins and biological parasites. In the Third World, chemical toxins wreak havoc causing autism. And then, even more scary, are the bacterial, fungal and protozoal parasites causing brain damage. Diet is a factor in the case of Alzheimer's and Parkinson's where plaque forms in the brain because the body is overloaded with sugar. Enzymes can't break it down fast enough. And then something as simple as the domestic cat carrying toxoplasma is said to be directly related to the rise in schizophrenia when cats became popular pets in the 1860s. And then all the problems with water-based sewage causing brain cancer . . .
It's all related. Environmental pollution is not just about charismatic megafauna of dolphins and big trees. It's about our emotional health as much as anything. That's something Jimi didn't know about . . . and we're all just now learning about it.
