Isn't It Grand Boys is a 1966 studio album by the Clancy Brothers and Tommy Makem.

[2] New York Times music critic, Robert Shelton, praised the album for its sound quality and presence.

About the singing, he noted: "The ensemble efforts have just enough polish to show a firm professionalism, and just enough rough edges to retain a native folk quality."

He singled out the songs "Nancy Whisky," "Isn't It Grand Boys," and "Westering Ho" for their "hearty virility.

"[3] All songs are traditional and were adapted and arranged by The Clancy Brothers and Tommy Makem, except where noted.
