Liam Clancy and Jean Redpath met him in New York's Greenwich Village in the early 1960s and we hear Bob himself acknowledge a debt to Liam as he performs a Scottish folksong, Lang A-Growing, at his first major New York concert in 1961.

We now also have the publisher demos, recorded soon after his return to the USA, among which are the earliest recordings of landmark songs such as Girl from the North Country and Bob Dylan's Dream, which were informed by his UK visit.
