I remember one of the shows in Chicago a few years ago, Glenn actually said something like "take all the pictures you want, just don't film us. We don't come to your job and film you."
He's usually so light hearted about it, it kind of surprised me when I read that he actually had said what he did Sunday night, right in the middle of a song. That would of brought me down--FAST! As for Don, no surprise there, in fact, it's gotten to the point that I almost expect it. Don't get me wrong, I love Don's talent and I love my Eagles but I don't like this kind of stuff. But ever since the whole flyers on the seats in Indy (wasn't it) about standing during the concert, nothing surprises me. I would never video them... EVER... because I'd be to afraid to be on the other end of Don or Glenn's wrath. Don't want to go there.
As for it ending up on YouTube... CRAP!!! It doesn't take away from their sells. And for some of us, that completely refuse to pay that kind of money for a front row or decent seat to one of their concerts, it's as close to a live show as I will probably ever get again. Just my opinion.
As for other artist overcoming it.... There are definitely some artist that absolutely EMBRACE it and post their own stuff on YouTube, etc.... As a small example, I've stated before how Styx goes so far as to grab your cameras, phones, etc and take them up on stage and do their own taping/picture taking before handing it back to the audience member. At their concert in June, Tommy, JY & Lawrence actually goofed and posed during a song when someone was making no secret of taping and after the song, Tommy said "Stick that on YouTube!".
It is what it is!! Times have changed and I wish the Eagles would lighten up.
