Truly sad. Hell he's 5 years older than my mom and she's in a nursing home unable to move basically, but still sharp mentally 5 years from now, who knows...). But Jesus, let's see, blowing your mind on drugs (luckily able to somewhat come through it unlike Syd Barrett), having both of your younger brothers die before you (as someone who has lost a younger sibling, yeah, that will fuck you up the rest of your life), a cousin who went nutso and took you to court, and a "manager" who controlled your entire life and tried to steal you blind. My mind would be mush too. I don't think he is near the end, but I do believe he is totally done creatively, or even as a "prop" on any kind of tour or anything. He was the ultimate man-child. Just never grew up, wrote some of the most brilliant music and melodies ever, but accompanied by just simple, juvenile even lyrics. He was just stuck in that "Great American Songbook" style of writing, from the 30s through the 50's, into the early 60's, but he could just never progress any further. A true savant, we will never see his likes again. Just a few favorites, again, the lyrics don't matter, it's the sound, the blend, the chords, the arrangements, that are true genius.
One of the most brilliant songs ever written, if you're musically inclined, just try to mentally figure the chord structure out as this is playing, where is the center? You can't do it..
again, such a deceptively simple song, but track where the chords go, every way you 'don't' expect them to go..
