Thanks for the link - the character Grandad played was Devil doubt, which appears in one of the Derbyshire plays, and there are similar lines, but not the exact ones - I am assuming that his memory was a true one - he could recall the exact same words every time, in the same timing and with gestures.

I have not been through all of them, and there seems to be no index of characters, so it is a matter of trawling through all of them - as I am not sure where some of the places are.

There must be quite a few people who remember that their grandparents had knowledge they could easily have aquired, and discover too late that it was significant -
