very interesting story. i knew about Brian Wilson's drug use and how that influenced his work in the Pet Sounds era, but i hadn't heard about the "censoring" of that particular track.
it was certainly a time for ego death themes in popular music. the Beatles' "Tomorrow Never Knows" is from 1966 as well, though it is much more overt.
