When we discuss the various setlists and what we want to hear we forget the audience the Stones are playing for... about 2% are hard core fans, the rest is just there because a Stones concert is a big event and a great show. They couldn't care less about the rare songs, really.
Many friends joined me to go to the Stones concert in Vienna in 2003, none of them had ever heard of something like a bootleg. They highly enjoyed the show, but thought that CYHMK was boring and they started to chat during Keith's set. That's the reality. The majority wants to hear the warhorses and the Stones know that.
And I don't think we will hear many rare songs this time. I think we will hear quite a lot of songs from the new album, though. So the setlist will be the usual warhorses, maximum one rare song and some new songs.
