describes that "Robert Lee Johnson" is his father. Claude was legally declared to be Robert Johnson's son in 1998. David Honeyboy Edwards, riding with Hammond through Greenwood, Mississippi, points out a yellow shotgun house where he says Johnson died. This location was mapped in the National Park Service photographic documentary project "Trail of the Hellhound". The film presents the first record of direct testimony by Johnson researcher Robert "Mack" McCormick. McCormick had not published previous research under his own name. In the film, McCormick discloses that Johnson's association with "satanic legends" started not merely as myth concocted by others, but had its roots in the death of Johnson's first wife during childbirth while he was away. Her family blamed Johnson, mainly for being an itinerant musician singing "the devil's music". McCormick asserts that Johnson was condemned so severely for her death that he gradually "became that person", associating himself with the devil in his music. Robert Johnson's death certificate is shown in the documentary, "answering some questions, but prompting even more." It had been located by blues researcher Gayle Dean Wardlow in 1968, and independently by McCormick, who also tracked down witnesses to events surrounding Johnson's poisoning and death. Interviewees Guitarists Keith Richards and Eric Clapton, blues researchers Gayle Dean Wardlow and Robert "Mack" McCormick, childhood acquaintance Wink Clark, Nat Richardson, a "juke house" owner's son, Delta blues musicians David Honeyboy Edwards and Johnny Shines, girlfriends Willie Mae Powell and 'Queen' Elizabeth, discovered son Claud Johnson, his son Gregory and grandson Richard, Greenwood Councillor David Jordan, and cemetery attendant Miller Carter were all interviewed for the film. Reception The film received positive reviews, especially from musicians and music critics. Upon its broadcast in 1992, UK producer and blues critic Neil Slaven, quoted later by Schroeder, wrote that the film "encompasses a detective story overlaid with folk memory, its interviews succinctly to the point, containing humor, superstition, and contextural information in equal parts." Folk singer Dave Van Ronk, reviewing the released video for Entertainment Weekly, wrote of its "lucid narration," and gave the film an "A," satisfied that it stayed focused on the music. Chicago Tribune reviewer Bill Dahl's four-star review termed the film "fascinating" and summarised, "Questions remain about this blues legend who claimed he sold his soul to achieve musical immortality, but this exceptional video answers a great many of them."
