Partial list of the songs from the 13-14 December 2021 Mudcat Worldwide Singaround (I had to leave in a hurry before proceedings ended), probably in the order in which they were performed. Thanks to MoorleyMan for the first part of the list; thanks to Felipa for additional information. Anyone who has access to any items that were performed after "McCassery (to the tune of Lord Franklin)", please post your information, and I'll edit it into this post (with attribution). If you have a copy of the chat that continues past McCassery, and you don't mind sharing it with me, please send it to me. Comments and corrections always welcome.
