Jim - many thanks for your response, and for taking the time to reply. My thread, as I'm sure you knew, was really trying to explore the rather shadowy borderland of what's been formally composed and what's not known as composed within the boundaries of the tradition. It's a fascinating subject and one that we'll never probably get to the bottom of. Which doesn't matter - it's the debate and the swapping of ideas that counts.

Thanks to all for contributing.
