Continuing our multi-episode series featuring Dylan's bands over the decades; tonight, we feature Dylan's tours in 1986 & 1987 with Tom Petty & The Heartbreakers and The Grateful Dead. On "Who Did It Better?" the song is "Knockin' on Heaven's Door," and we ask you who did it better live, Bob Dylan with Tom Petty and the Heartbreakers in 1986 or Bob Dylan with The Grateful Dead in 1987? Go to our Twitter page @RainTrains and vote between the two versions.
