Trawling through mentions of 19th century pipers in Chester and found this from the Chester Chronicle 26 April 1833, admittedly there's only a brief mention of bagpipes and the music, but the story is a familiar one from folk songs. And the epilogue shows a firm belief ineven at this date.
PLUCKING A NOODLE - A countryman named Francis Hanmer who said he came from Bryngwylla near Oswestry, charged Ruth Jones, a female of common repute, with stealing his watch. The complainant said he came to Chester on 27th February last, to sell a horse for his master, Mr. Lewis, of the Brook House, near Oswestry. In the evening he strolled out into Eastgate-street, where he met with Miss Jones, who invited her to accompany her to the Three Tuns in Frodsham-street. He, not liking to refuse Jones's request, went with her to the Tuns, where he found a number of Cyprians, engaged in a mazy dance. Aroused by the discordant squeakings of the Irish bag-pipes, on which a fellow was discoursing a most exhilarating music, he rose up from his seat and, as he expressed it, "had a bit of a hop - a three-handed reel with four females and during this time I lost my watch". He could not swear that she took it from him, but she was the nearest to him while engaged in the dance.
Alderman Morris (addressing Hanmer) asked him if he were married. Hanmer with a sheepish look replied "Oh yes Sir, I have a wife and five children". - Ald. Morris, "You ought to be ashamed of yourself for being in such company. What will your wife say when she hears of this transaction?" Hanmer, "I'll not tell her anything about it" - As there was no evidence to prove that Jones stole the watch, she was discharged.
Hanmer visited the police office on Sunday evening, and while there he told one of the officers, that if the magistrates did not commit Ruth Jones, there was a "cunning fellow" (a sorcerer) that lived in his neighbourhood, and that he would engage him to bewitch Ruth: and that he would bring her, watch and all, across hedge and ditch, flying from Chester to Bryngwylla. One thing is quite clear, poor Hanmer is no conjuror!
