"If I made records for my own pleasure, I would only record Charley Patton songs." - Bob Dylan
Bob Dylan and The Fifth Sex ???
File THIS one under "mysteries" I guess. Bob Dylan, Ph.D writes a forbidden book! One is listed for sale on Abe books, but the description says "musty smell" so I'd wait for the Kindle edition. 1969 Publication date. And you wondered what he was doing after the motorcycle accident?
