Hi PFR. I have no knowledge of photos at all, and respect to those who do. However, I do archive audio. And, I think it unreasonable to allow my work to be given away willy-nilly to people who just think they should be "allowed" to own it, (for no money). I also have total contempt for people recording gigs without the artists permission. On the rare occasions when I play in public, I keep a beady eye on the audience... Sessions ...No problem, People will say, "Can you play such and such a tune, I want to learn it" My answer is "Fine....Will probably get it wrong now!" And I normally did!
Ny point being, courtesy is everything. Ask nicely, and you shall be rewarded....Bootleg something, expect a slap in the mouth. I'm first in the line!
