This Scotsman has danced the Dark Morris

We were taught it and danced it at the International Discworld convention in 2016

Quote ---

In the spring, on Mayday, Morris dancers "dance the sun up" lest it fail to warm the land for the coming summer. This custom is widely observed across the Multiverse (even on worlds where the Carbon Dioxide freezes in Winter) and especially on the Discworld, where the threat of stories  and legends is real and such rites are more than just quaint old customs. Mayday is a festive occasion and many will drag themselves out of bed before dawn to watch and cheer on the dancers and the sun. Later in the day, perhaps after a nap, there will be more dancing, Morris as well as the maypole, with feasting and frolic and beer.

On or near the first of Ember  there is another dance, the last of the year. There is no crowd of cheering spectators, no merriment, no music, no sound. The dancers trade their bright white beribboned costumes for black shrouds and perform in darkness and silence without bells, sticks or swords (or better, with bells of octiron  that create a lacy counter-tinkle of silences}. This is the Dark Morris, without which winter may not arrive to complete the cycle, water the land with snow and prepare for the renewal of spring. Winter begets summer, death begets life, and a city-sized sun that travels faster than its own light needs all the help it can get.
