Yes Nick I do have many interesting stories from various branches of my family but none of relevance re traditional music except for one family in Cornwall in the early 1800s. The patriarch was an African who became a music teacher who fathered a number of sons who were musicians and like wise their children. Some of their descendants are still musicians in the States.

Am I familiar with the area? Yes I am an East Ender from Old Ford, Bow.

I doubt also whether the jellied eels stalls in the open street markets would pass H & S today.
