It is not smart, or logical.
There is no copyright consequence of uploading audience recordings. They are not the same recordings. There would only be breach of copyright if the official recording was being made available for download.
I have too fully agree with you on this one, Dustyvalentino; even though I could also agree that being legally and morally right does not necessarily means that you won't run into troubles, in this sad world.
Well, your Honor, the defense would like to call a witness - and not your average witness:
"I am against this lawsuit. It was said TV would be the end of cinema, it was said tapes would kill records and CD burners would kill CD's, but that's not true. Technology will always progress. The only real danger comes from countries which practise industrial piracy. I've always encouraged the recordings of my concerts. From the stage I had fun seeing all those little red lights of recorders and these microphones hold by fans. That's no danger and even quite cool. Fans who buy bootlegs already own all the official albums anyway. They do us no harm and I find these raids against bootlegs shops ridiculous."
