A description of the experience
The Fairy-Faith in Celtic Countries, by W.Y. Evans-Wentz, 
The Fairy Tune.--'William Cain, of Glen Helen (formerly Rhenass), was going home in the evening across the mountains near Brook's Park, when he heard music down below in a glen, and saw there a great glass house like a palace, all lit up. He stopped to listen, and when he had the new tune he went home to practise it on his fiddle; and recently he played the same fairy tune at Miss Sophia Morrison's Manx entertainment in Peel.'
