Hi BlackAcorn - Sorry, only just seen your question. Yes, I was resident with Abram pace egg players and played various roles in their play. We used to perform it on Good Friday in Lancaster as part of the maritime festival while the Lancaster pace eggers performed on Easter Saturday.

I was also, in dwscending order of how often I performed, a musician , dancer and king at the Abram circle dance :-)

The late Eddie Cass used to document our shenanigans quite often but it was more in relation to Pace Egging than mumming. Still, it may be worth you looking at his work as a starting point to help your research. Eddie was a Lancastrian but a lot of his work is held by the University of Sheffield.

Good luck with your research and let us know how you get on

Cheers
