Ha, I'm an idiot. This is why you should always (still! even in 2018!) look at a band's own webpage.
The Assunta Spina I just mentioned event, featuring the #Badwills is also on in #Edinburgh this Saturday at #Summerhall.

But I think my night out budget is spent already for the month 😢 Everyone else should go though, it will be wild.

So, the #Badwills are an #Edinburgh based band doing arrangements of Italian folk songs, tarantella, pizzicarella, etc. Not something I know much about but oh my do they do a footstomping live show.
My feet may feature in this video: https://www.youtube.com/watch?v=Cwri8548Abo though the audio is a bit more sedate than their #Summerhall shows.
There's a couple of albums on Bandcamp, which I haven't listened through yet: https://thebadwills.bandcamp.com/

And of course, they have covered Bella Ciao: https://www.youtube.com/watch?v=vNtsRncbkgU
