The seals are very fond of music. Everywhere I went people told me that, but I was never fortunate enough to hear first hand the music that belongs to them. I believe there is music that remains privately in the minds of the country people of the West, but can only give here a few pieces that have found their way into print. I shall put first a ballad, "The Grey Selchie of Sule Skerrie," and, last, a few notes which were sung by a seal off the island of Skomer, Pembrokeshire, in 1946, and recorded there by Dr. Ludwig Koch. These two have moved me more than the others.
