Mama (1)" and "Rock Me Mama (2)". According to Ketch Secor of the Nashville band Old Crow Medicine Show, Bob Dylan attributed the lyrics of "Rock Me Mama" to Arthur "Big Boy" Crudup who in turn attributed them to Big Bill Broonzy. Both "Rock Me Mama" and "Sweet Amarillo" were eventually completed and recorded by the Nashville band Old Crow Medicine Show, who credited Bob Dylan as co-writer. "Wagon Wheel" was released in 2004 (and subsequently covered by many other artists, including Darius Rucker) and "Sweet Amarillo" was released in 2014. Critical reception Most critics at the time responded unfavorably. Robert Christgau graded it a "C" in Creem, described the album as "two middling Dylan songs, four good original Bobby voices, and a lot of Schmylan music". Jon Landau wrote in Rolling Stone that "it is every bit as inept, amateurish and embarrassing as Self Portrait. And it has all the earmarks of a deliberate courting of commercial disaster, a flirtation that is apparently part of an attempt to free himself from previously imposed obligations derived from his audience." The album spawned a significant hit in "Knockin' on Heaven's Door", which would be covered by acts such as Eric Clapton and Guns N' Roses. 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. Legacy 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. Peckinpah's film was released to mixed reviews. Years later, critical re-evaluation of Peckinpah's film would lead many to regard it as one of his major works, a revisionist view aided by the restoration of Peckinpah's original cut in 1984. After witnessing firsthand Peckinpah's battles with MGM, Dylan had his own problems with Columbia Records. After years of minimal activity, Dylan had lost Columbia's patience, and when negotiations for a renewed contract began in 1972, the label (except for Clive Davis) had little interest in being generous. "Early in 1973 I finally did conclude negotiations for a new contract with Bob," wrote Clive Davis in
