Syd Barrett

There's a lot of mystery about Syd Barrett's life after Pink Floyd.

Was he a drug casualty that had difficulty functioning? (What's commonly believed)

I suspect he wasn't a damaged mind. I believe he couldn't handle fame due to his severe mental illness. Being famous wasn't good for his mental health. It caused a psychotic break. So rumors were manufactured to keep him out of the limelight.

On the sly, he was contributing to Dark Side Of The Moon, Wish You Were Here, and The Wall. In fact, The Wall is kind of his autobiography.
