!! it does seem like either Copperpot's message was really inspiring to Dave/anyone else who could have noticed it, or, it coincided with everyone in the band feeling ready and engaged to create these deeper concerts. It seems like it will continue through to the end of the tour.
they do have each night a few groups to really consider, when they have time to think about it! ...
* long time fans
* people who will become fans due to the concert
* anyone who is with their lover and so it's kind of a concert-date
to consider in writing the concert; while regular fans will pretty much be ok with anything...
That last one is more significant than one would think!
They are one of the more romantic groups also playing amazing music going today and sometimes probably do try to acknowledge that in choosing songs, possibly, even the cause of closing with Shake Me.. even some (though not all :P) long time fans there in a romantic state of mind would be happy.
