"Howard, you say read/study more but you clearly have not bothered reading the posts of the one you are criticising - I've used books: you will not find, e.g., "The Northumbrian Bagpipes" or "The Tyne Exiles Lament" in google/on the web"
No? Guess what the top google result for 'tyne+exile's+lament+lyrics' is.

Interestingly enough, the tune is based on the Banks of the Dee, a song written by a Scotsman. I understand that the tune itself appeared in an early 1700s dancebook from London, but do you think that the author of the Exile's Lament based it on that obscure source rather than on the singing of Scottish neighbours?
