For thou must go with me tonight,
And taste of Fairy-land's delight."
Robin, hearing this, rose and went to him. There were with King Oberon many fairies, all attired in green. All these, with King Oberon, did welcome Robin Goodfellow into their company. Oberon took Robin by the hand and led him a fair dance: their musician had an excellent bag-pipe made of a wren's quill and the skin of a Greenland fly. This pipe was so shrill and so sweet that a Scottish pipe, compared to it, would no more come near it than a Jew's-harp doth to an Irish harp. After they had danced, King Oberon said to Robin:—
"Whene'er you hear the piper blow,
Round and round the fairies go!
And nightly you must with us dance,
In meadows where the moonbeams glance,
And make the circle, hand in hand—
That is the law of Fairy-land!
There thou shalt see what no man knows;
