Montanero, Big Bad John was/is a great song, But, i believe that it does not qualify as early Rap because it doesn't really rhyme. Albeit, it's not bad blank verse. Dylan's early anthems all rhyme. He really was more a poet who set his poems to music, as opposed to a lyricist who put his words to music. Google the lyrics to The Times They Are A Changing" and "Subterranean Homesick Blues". I think that will illustrate the difference. ( P.S. Now I'm laughing at myself. All of a sudden I'm a geezer music critic. Hope you guys don't mind.)
