Bill D mentions Jeannie Robertson (if you doubt him, listen to McCrimmond's Lament) and Davy Stewart. I would be inclined to suggest Phoebe Smith. So what do we learn from this - all 3 are Travellers. It may be a very crude measure, and of course you can fill the thread with exceptions, but yes I believe that the gypsy singers have a style which is essentially expressive/emotional and the gorgio singers a style which is less so, more declamatory, more removed. When Herga Kitty says there is a school of thought that says English traditional singing shouldn't be expressive, though I would not be so prescriptive as to say "shouldn't", I would certainly say that historically this is true of England; less so of Scotland/Ireland; not at all of the Travelling singers even where, like Phoebe, or the Kent/Sussex based Smiths, they never travelled out of England.
