During the summer of 1953, Harley contracted polio, causing him to spend four years in hospital between the ages of three and 16. He underwent two major surgeries in 1963 and 1966. After recovering from the first operation at the age of 12, Harley was introduced to the poetry of T. S. Eliot and D. H. Lawrence, the prose of John Steinbeck, Virginia Woolf and Ernest Hemingway, and the music of Bob Dylan, which inspired him to a career of words and music.
