Brian Wilson's 'Smile.'
I'm new to the board and don't know whether this issue has been raised: was the story based in part on Brian Wilson's legendary 1966 "Smile" project? There are some interesting paralells: pop music genius and surreal lyricist too far ahead of their time, tapes that many know about but few have heard, even a protagonist named Wilson.
Coincidence? I think not, but I bet someone in this group knows.
