In his book No One Else Could Play That Tune Clinton Heylin notes that the only contemporary radio interview in which Bob Dylan discussed Blood On The Tracks was with Mary Travers but he carefully steered her away from it after a brief exchange. This is said interview (just the talk, the commercials and music are edited out). They also talk Woody Guthrie, topical songs, and about the then forthcoming Basement Tapes release. At one stage the conversation gets a little philosophical until Bob points out to Travers that she is crossing another one of his red lines.
