I’m not sure what this is about but here’s Lucy’s singing with an Italian band the song “So Does Your Mother” in February 2017. Their facebook page explains how this came about (it’s translated from Italian and I don’t know Italian so I have no clue if it’s correct)

A few months ago, we played with our friend Lucy Lawless and we had so much fun to do this piece of space waltz called out on the streets ". of course we sdymmato to duty. It's been a wonderful experience and as you can see we had fun. Unfortunately that day our beautiful gian Maria wasn't there and has been replaced by one of the founding members of this project Francesco Fusco. I hope you enjoy this video to see how we have fun playing!
