Not just in terms of setlist, in terms of the show in general
I watched Live From London for the first time this morning... compare the first two songs to the first two songs of the Crush Tour DVD.... not only are they the same songs, but they are played in almost exactly the same way.
But yeah, throwing in some new stuff would be great

make it so that the audience are never quite sure what they're gonna get
I actually don't see how they can do almost the same show every night and not get bored with it
Keep On Rockin'
