Wow... the people here must be getting dumber. A few years ago, people had the intelligence not to share convention demos like this. Did you ever stop to think why it says "property of Queen Productions"? It was to stop people from recording the songs, along with the threat that if they found out that the songs were being recorded, they would stop playing the songs at the conventions.
So, keep 'em coming... you're going to ruin it for everyone.
Well, actually the consequences this time might even go further then that. Chances are that if Brian finds out that Kashoggy (which is by the way labelled as 'Party' in the archives!!) and Rain Must Fall specifically are in here, the person that plays the tracks on the conventions will not be hearing anything new anymore himself!
(But then again, to some QZ'ers that must sound like music to their ears...)
It actually indeed DOES keep the anthology sets further away from being released (if ever).
See, 'hoarding' as people tend to call it, sometimes actually does serve a higher purpose.
It's not that I don't grant people the pleasure of hearing these tracks - not at all. It's just that I happen to know that the leaking of these tracks might harm some persons and as consequence the entire Queen fanbase.
(And the fact that these are 'just' the convention recordings and not the soundboards, does not make a difference.)
