UTW and AT - I think you both have pretty much hit the nail on the head as to what may have happened. I believe many people, including myself, think this whole think could and should have been handled differently. In my opinion, there should have been an official announcement coming from Irving stating the remaining Eagles would be performing as soon as the festival was announced with some kind of statement stating this was with the blessing of the Frey family. Instead there was no announcement, days and days of speculation and then finally Don's "So I'm Told" comment. By the time they gave the interview with iheart radio, almost a month had gone by. And, judging from FB comments I have seen, most people never heard the radio interview. This of course caused more speculation and criticism towards the band for being only about money. This all could have been avoided if Irving, as their manager, had handled it properly.
I do not think there is anyone who has any objection to Deacon playing with Don, Joe and Tim to honor his father. He will be playing with three people who care a great deal for him and will do everything possible to make sure he is comfortable.
