The notes say this dance was “written for Dr. Peter McBryde, a teacher, and his wife, Marion, who have contributed much to Scottish Country Dancing in Canada through the Teachers’ Association and Tactalk.”
A footnote explains that a Reef Knot tied incorrectly is known as a ‘Granny Knot’. In the S.C.D. formation called ‘The Knot’, dancers turn with the left hands back to places, whereas in the last 4 bars of this dance they turn to places with the right hands, suggesting the above title.
