I wonder how much money this pretending to come from different towns actually makes them? Is it really worth the risk of getting done for gaining pecuniary advantage by deception or whatever...what would the offence be? Perhaps a lawyer could elucidate?
The Dubliners should maybe have thought of this(or the Houghton Weavers, or the Oldham Tinkers, come to that). They could have websites calling themselves the Skegnessers, or the Carlislers or whatever, and got lots more gigs.
