Tim Leary, the ex-Harvard professor who chucked that career to advocate for the benefits of LSD--the man who coined the phrase "Tune in, Turn on, Drop out"--wrote a novel in 1976, and Kurt reviewed it. "In the Celtic tradition, which Leary is now invoking, he appears as the boy Gwion (pronounced "Finn"), become all-wise by accidentally sipping the witch Cerridwen's brew, as Leary sipped Albert Hoffman's, who is pursued by her and changes into hare, fish, bird before she finally swallows him as a grain of wheat and then bears him as a son, the half-divine riddling poet Taliesin." Kurt and Tim were both magicians, brothers in the esoteric arts. It's unclear if this review was ever published, but you can read it here.
