That's crazy man, sad that these things happen to people too.
When somebody is completely down and out, unless you are there also or are a social worker, it's hard to pay attention.
I was tired of having studio rearranged and stuff missing or borrowed, or at the very least buying stuff for people or giving them a ride not knowing if they were out to score drugs. Some of us were older than the others who were at the studio and had little tolerance for the rock and roll lifestyle.
Every musician who was at the studio were very happy to be there, pumped up, and admittedly had high hopes. My guess is that he had no interest in jamming with such hacks like ourselves.
It's just weird when you meet somebody who said they were there, knew Metallica, toured, etc, etc and basically for us amateurs it's just hard to relate to a very talented person who helped write the book on speed metal or any other genre. It could be the guy who delivers your mail and maybe they were very famous for a few years in the '80s on the Sunset strip or hang out with more famous folk daily. One just doesn't know who that stranger musician is until you really know them. For a lot of people, this most talented of singers, and one many successful singers look up to today as an influence, was mostly known as a very good street artist doing sand work at the beach along with the other down and out artists.
Anyway, the next time a homeless person or junkie comes up and says they used to play or sing, I will jam with them. If I didn't know Charlie Parker, Jaco, or Keith Richards, I would think they were the local beach person building sand castles for a few bucks a day.
