Surely the greatest omission is the Leader catalogue, whose output included the Percy Grainger recordings, the Masters of Irish Music series, plus various solo Lps of singers like Eddie Butcher, John Maguire, Walter Pardon, Cecilia Costello, George Dunn, the Copper Family and Jack Elliott. And that's not to mention some very fine LPs of American musicians and singers, plus the Edith Fowke edited compilation, Far Canadian Fields.

Unfortunately, Leader went under in the oil crisis of the 1970s, the catalogue was sold, and practically nothing from that catalogue has been seen from that day to this. A whole chunk musical heritage obliterated.
