Grant Green would have been better off if he had never left St. Louis. Blue Note came to St. Louis looking for Grant Green, he didn't go looking for Blue Note. He would not have become famous, but he might still be alive, and as well off as other St. Louis musicians. St. Louis takes care of it's musicians; but when they're destitute after being rich and famous, that's the last thing they want out. (once you become famous, people think you're rich)
I can think of a musician who was rich and famous, but became destitute and in bad health. Naturally they wanted to keep it a secret. When word got out, not only did they get help with medical bills, but attorneys helped them recoup millions in royalities.
All the St. Louis musicians who I know personally, live on the same economic scale as someone with a good job; they have a nice home and automobile, plus live good.
When word gets out about a musician being destitute, (right now I'm thinking of local musicians) the first thing that happens is a "benefit"; any famous musicians have to show up, and perform for free. Rich patrons can't just donate $20; they have to contribute real money, because their names will be on a plaque with how much they donated. Every musician in St. Louis has to show up. If they're too old to perform, at least they were seen. For fans like me, it's the place to see, and be seen by people you haven't seen for ages. Everybody has a good time, and we all benefit.
I'm glad Chuck Berry is still alive, he was always instrumental in benefits. Like I said in the beginning, no musician whose been famous wants anyone to know when they get destitute; a big mistake in St. Louis.
Enjoy the music.
