Heptonstall Pace Egg Play is a traditional Mumming Play

Some of these UK traditions - it's like we're all not even speaking English any more. Is Heptonstall Pace a place? Or is there something called a "Pace Egg Play," in which what is Pace about and what is an egg play? I have an idea about Mumming, so is this a dance that reenacts some event with the easter bunny or does it go way back into pagan traditions about something else?

Curious folks across the pond await the explanation. (I could look it up but am interested to see what the answer is here.) :)
