I'd agree 'the impact of Covid 19 has been felt across the uk music industry'; if its an industry. For many of us it was a way of life and Folk is maybe unusual that most of those who went were performers though maybe not artists trying to make a living.
There has been little lament on Mudcat on the absence of folk clubs, which surely impacts on artists as well as regulars and venues. Discussion of songs is busier than ever. Rearranging the deck chairs.
