Mrs Kate's home page is here. . She is a working folksinger, contributing her own music to the river of our folksinging legacy, and this kind of bullying from a bureaucratic institution is unforgiveable.
I think Declan Mcullough might enjoy making some noise about this story, and if Kate doesn't mind, I will send it to him. He writes extensively about the confused and the stupid management of issues such as permissions, copyrights, encryption, Net taxes, and legal blunders, mostly relating to internet-driven changes. Please ask Kate if she would mind and if not I will at least send it to him to see if he wants to circulate it.
