Towards the end of the 1950s four young Irishmen who had emigrated to North America to pursue fame & fortune in the theatre formed a singing group. Intending only to play the small taverns & clubs of Greenwich Village two lucky breaks propelled them to stardom. A fortuitous guess spot on the Ed Sullivan Show turning into 19 minutes live to 80 million people. The rest as they say is history. By the 1960s they were the best-known Irishmen in the world playing to packed houses from Sydney to San Francisco. Then years later after 40 profitable record albums countless TV appearances & sell-out concerts they broke up each wanting to pursue their individual interests. Now nearly twenty years later we look back on their phenomenon & the times. We visit the Clancys & Makems Irish roots the Greenwich Village pubs they started in & even catch a glimpse of the Ed Sullivan Show that changed their careers. Interviews with Bob Dylan (his first on film in many years) Mary Travers & New York Mayor Ed Koch among others illustrate the pronounced influence The Clancy Brothers & Tommy Makem have had. Interwoven with his look back in their sold-out reunion concert at Lincoln Center. That night as so many in the past the audience was a cross-section of humanity revelling in the Irishness of us all.
