Frank Sidgwick, The Sources and Analogues of 'A Midsummer-Night's Dream'… (1908)
“ After they had danced, King Obreon spake to his son, Robin Good-fellow, in this manner—When e'er you hear my piper blow, From thy bed see that thou go; For nightly you must with us dance, When we in circles round do prance. I love thee, son, and by the hand I carry thee to Fairy Land, Where thou shalt see what no man knows: Such love thee King Obreon owes. So marched they in good manner (with their piper before) to the Fairy Land: there did King Obreon show Robin Good-fellow many secrets, which he never did open to the world. ”
