Good point, Border Reiver, it´s a very delicate situation, and that´s why I thank Mimmo to share some of that stuff he has.
For a collector, there are certain items that you got paying big amounts of money, or that you got dealing with the previous owners and you got them with an "advert" like "this is just for you, don´t share it or you won´t get anything else" etc etc etc. It´s complicate, but there are stuff that you cannot share with others for whatever the reasons, but you can talk about them. You have to decide if you keep that items just for you and nobody else will know they exists, or you can decide to share the existence of this items even you can not share them (let other people listen to them or have them).
I don´t mind the reason why someone who has those items can not, or doesn´t want to share them. It´s personnal, I can not force anyone to share anything if they don't can/want. I´m more than happy just knowing this items exist.
I´d love to listen to that special Tunnel Of Love version, but I´m happy to know they exist even I can not listen to it. I know that other people can't stand this and they rather don´t know about things they can not get their hands on. It's hard to know such a nice thing exist and you can't listen to it, but, you never know... we all know by the MK biographies that "Summer's Comming My Way" existed and then, many years later, one of the owners of it decides to show it in a radio and allow the fans to listen at least a portion of it.
But if we attack the owners of those items, the only thing we are going to achieve is that they decide not allow anyone to listen to it in the future, or to let others know that other fantastic items. For me is just a matter of basic respect. I more than open to let Mimmo to talk to me about millions of things that I am not to listen by whatever the reason. The simple fact that probably the biggest collector in the world about MK decides to share the knowledge of those items is more than enough for me.
