Stewart, you must get yourself a copy of "Alawon John Thomas: A fiddler's tune book from eighteenth-century Wales", National Library of Wales 2004, ISBN 1 86225 042 1. It isn't 'just' Welsh tunes as it is the collection of a 'jobbing' Welsh fiddler of the time, and he would need to know the local favourites as well as the fad tunes of the time. This particular book is part of Cass Meurig's ... doctoral? ... thesis and she's an excellent crythor / fiddler herself.

One of the Ned Puws is in it. I could scan you the 3 I have if you send me an email address.
