Jed makes a very good point here. When I comes to stuff that's released to the public, especially from a live performance, you really want to maintain control over whether it gets wider distribution.

Case in point:   I did a concert a few years ago that was recorded and part of it was filmed. I had no idea that any of this was going to go any further, but someone posted a couple of songs I sang on the internet. Had I been asked first, I would have stamped upon it heavily because, although it was okay, the selections were far from my best performances, and I didn't really want them out there in front of God and everybody. But there they were!

I'd really like to be asked.
