Got it in one Dead Horse, the one thing you see from source material is the complaint that youngsters don't want to take part (circa 1890's et al!). Well, Morris aint dead yet and wont be for some time to come, whatever your take on it.

As long as people enjoy doing it, it'll survive. The moment it becomes a strict re-enactment or 'heritage' show, it's days are numbered. However, I have full faith in the benign anarchy of the Morris world in all it's forms!
