The Clancy Brothers were an influential Irish folk group, best known for their arrangements traditional Irish ballads, drinking songs, rebel songs, and sea shanties.
They were best known for their work in New York in the 1960s with Tommy Makem (as Tommy Makem and the Clancy Brothers), and are credited with popularizing Irish folk music in America.
The brothers (originally Paddy, Tom, and Liam) emigrated to the USA in the 1950s, and recorded The Rising of the Moon, their first album, in 1956. Their big break came in 1961, when they appeared the Ed Sullivan Show in front of a TV audience of 40 million.
