Just to say, we didn't copyrighted anything. There is no copyright on any of our cassettes in fact; the copyright mention you can find on bandcamp can not be removed - I think it's a copyright mention for the bandcamp trademark and / or design.
Also this type of behaviour is common in other musical and art forms : call it sampling (which created whole music forms), tribute, or pop art (I think someone wrote about Marcel Duchamp ?)or what you want, it's another discussion.
Oh, and Sam tried to take contact too, as he told Mr Mike Yates.
We have made several mistakes - and we apologised for them - but treating us several times of thieves is becoming a little annoying Mr Caroll, even if it seems "amusing" for you; all I can say is that we took this matter seriously and with all possible respect as soon as we heard of it. Sorry for making you miss University Challenge, maybe you can find a re - run on the Internet.
