I'm 100% backing their decision to play the whole new record. I'm also very glad they left out The Number of the Beast, The Trooper and especially Wrathchild. I was waiting for this move for years. They cleverly picked the 5 classic songs. With the exception of Hallowed and IM (which are impossible to leave out) the other songs are from the after PoM period that was extensively covered in the last tour. The return of 2 minutes was obvious since it fits the war atmosphere of the new album. "The Evil" also returns.
It is a nice strategy not to play some of the classics for a couple of tours. That way the fans will miss them and happilly see them return in the setlist. For example I was bored with listening to "2 minutes" and "The evil" tour after tour. Now -after they were omitted for a couple of tours- I think they will sound less tiring, more fresh and I actually feel the need to listen to them. For sure it will be the same with "The Number" when it returns to the set in the (I hope not so near) future. I think that "Fear" is the song that will need to have some rest in the next tours...
I hope that some negative comments that will be heard across the globe about Maiden not playing the classics and so on, will not discourage them and make them change the setlist mid-tour. I think they will not, cause they are stubborn (and although sometimes it is not a good thing, I think this time will be for the Greater Good
