OK,
Just to clarify, I am exploring issues like:
- How widespread was the tradition (i.e. playing both at the same time)
- Is it a descendant of the pipe and tabor tradition or just a serendipitous similarity?
- what does it tell us about English percussion traditions?
There may be no clear answers to these, but I am trying to assemble all the available evidence. Or has the trail just gone cold? Grateful for any information.
