The Clancy Brothers' Greatest Hits is an original studio album of some of The Clancy Brothers' most popular hits re-recorded with Louis Killen. The Clancys had performed each of these songs previously with different arrangements with their former partner Tommy Makem in the 1960s. This was the group's first of three albums for Vanguard Records, their last album with Killen, and the final album they would release for almost a decade. The recording was initially released as a double album. A backing musician on a few of the tracks is Don McLean, best known for his song "American Pie". In 2000, Vanguard re-released the album on a CD entitled The Best of the Vanguard Years. In addition to including the entirety of the Greatest Hits album, the CD included four previously unreleased tracks from the Clancy Brothers' follow-up album Live! (1982).
