I think many established bands fall into this trap. Eg: Iron Maiden, Aerosmith.

But compare it to Metallica setlists, you don't know what you are going to get. They also bring in a lot of songs that they haven't played for a while. Maybe a lot of that is down to having a new bass player, but I def. think BJ should take a leaf out of Metallica's book in this respect.

Also, Metallica record each show soundboard & u can pay for your show over the internet which I think is a great idea.
