 Years later, "Knockin' On Heaven's Door" endured as a popular favorite among critics and fans as well as a concert staple, with its inspirational tone and lyrics regarding impending death.Some retrospective reviews see it as a spare, beautiful departure from form and a worthy effort as a whole fully in line with the thrust of the film.After Peckinpah completed his own cut of "Pat Garrett and Billy the Kid", MGM re-cut the film without his input, removing several significant scenes and re-shuffling most of Dylan's music in the process.
