Unique voice and a damn good songwriter, too. My favorites were "I Know Where Love Lives" and "Sure Love." He also did a very good remake of "Five O'Clock World," a song, so the story goes, that he had loved for years and asked his producer, Allen Reynolds, if he could see about getting it for him to record -- at which point Reynolds told Ketchum, "Hal, I wrote that song!" Indeed he had, and Ketchum apparently had no idea!
