I think I may have come across said drummer. Well, their FB page, which has videos of them banging a drum in some fields, presumably in Stafford. We have discussed this person on here before. What led me to search for their FB page was that I saw them tonight at about 9:30pm at the top of the old Doxey Road bridge, which is now pedestrianised, furiously waving a torch about (maybe mobile with a light on?) and dancing and stomping about.
