Dylanesque/Band start, and the intro is just right as a blast and in length. The fairly quiet voice and the harmonica makes a great contrast. "...little sign/Coming back..." is a slightly odd jump in style; the second time , it's harmonica then "Coming back" and that has more impact. Think about perhaps a short blast of harmonica in the first "...little sign/TOOTOOT slideguitar/Coming back". We're talking about lifting an already really good and attention grabbign and arresting song here BTW
