It seems that such is the power of CM that even to be mentioned in passing, even innocently, in these pages is the rocky road to perdition ...

The name Castle Communications seemed somehow familiar, so I set out in search, but it only turned out that I have a Ralph McTell CD from them, no old vinyls.

However, I also did a web search. and found this:

:-) See what I mean?

But I agree that they don't seem to be related to our two con men though ...
