Peter, Paul & Mary, Joan Baez and Bob Dylan were frequent performers at the Newport Folk Song Festival during the years 1963 to 1966. This music documentary captures these seminal artists and many others, including Donovan and Judy Collins, while performing for the enthusiastic audiences of the festival. Particular attention is paid to the performers' political and social convictions in this vital document of the times, as their comments and asides introducing their songs are retained. Despite the political tone of the so-called "protest music" performed by many, other less-controversial folk-music genres were also brought to the screen in this feature, and the blues are not overlooked.
