It's interesting to note that the 2014 press release says "[it is likely this is] the last time fans will EVER hear some of these songs played live."
Okay, I can see that being true for maybe less than a quarter of the set: Moonchild, The Prisoner, SSOASS, and Aces High. Granted, the word "some" is very ambiguous, but come on... bit of a stretch there, guys...
Then again, maybe they really are retiring a lot of the overplayed tunes we've come to expect. It'd be pretty refreshing if they did another tour like 2010, with a less "hits"-heavy approach.
