A winning comedy that let the Fab Four embrace the image that had been made of them, Help! is as underrated as the album that inspired it.

In Bob Dylan’s memoir Chronicles Volume One, he described the relationship he felt with the Route 61 that became the title of his sixth studio album for Columbia Records, Highway 61 Revisited.
