This intimate, confessional and highly cinematic documentary film charts the remarkable rise to fame of these devil-may-care Irish singers, from their small-town beginnings in County Tipperary in Ireland to the folk hey-day of Greenwich Village in the Sixties where they played for JFK and out-sold the Beatles.

Featuring exclusive footage, interviews and additional performances from the man Bob Dylan called "the best ballad singer I ever heard in my whole life. Still is, probably".
