That picture is hilarious.
I think their message is intentional and strategic - the guys know that probably 90% of ticket revenue comes from people who are over 45 who do not want to stand for 3 hours at a rock concert. The message is that their show is meant to be enjoyed like a performance you would enjoy at the symphony or opera or even on Broadway. There may be a point where the music gets rockin' and the audience stands, but otherwise, it is "an evening of music with the Eagles." It is not a Katy Perry or Justin Timberlake concert, the same rules do not apply. You can expect to be comfortable and not bothered by your neighbors. They need to keep the oldsters who can afford the tickets comfortable and coming back show after show. (And yes, I know there are many of us who are not oldsters, especially not me
) Unfortunate, though, that the message seems to be so "strong" Down Under, don't know what happened there.
