From what I've read, he was going insane anyway, LSD (his drug of choice) just sped up the process.
I was glad to read, the members of Pink Floyd made sure he was VERY well taken care of. There was an article a couple years back who got pictures of him riding his bike in the small town he lived in, he was living alone, painting, writing, and completely shunned the press and the fans. They said he was writing a history of art...
He was a strange, enigmatic man, who inspired and intrigued. RIP Syd, there will never be another.
"The members of Pink Floyd made sure he was very well taken care of.Living alone painting,writing..."That's my understanding as well.I believe he also made at least one album-"The Madcap Laughs Back."
