In 2019, a new Sheendom tradition was born when @master_crowley wrote the lyrics to a Michael Sheen-themed version of The Twelve Days of Christmas, and Michael responded with some video tweets, singing about mint choc-chip icecream, onion peels and sheep.
The following year, he took part again and sang a newly-penned version for 2020 with references to Nutella, orange (red) hoodies and zoom calls.
A version has been written for 2021 but we are yet to see if he will respond!
The tweets below are all in date order, with the newest first, and include other Christmassy fandom things that happened.
