LC, your three last posts began with "Oh". Feeling overly emotional today?
A period they seem to be trying to forget, sadly.
I don't think they're forgetting any period;
Iron Maiden : Iron Maiden, Sanctuary, Phantom Of The Opera
Killers : Wrathchild
Number Of The Beast : The Number Of The Beast, Run To The Hills, Children Of The Damned
Piece Of Mind : The Trooper, Revelations
Powerslave : 2 Minutes To Midnight
Somewhere In Time : Heaven Can Wait
Seventh Son Of The Seventh Son : The Evil That Men Do
Fear Of The Dark : Fear Of The Dark
The X Factor : Lord Of The Flies, Sign Of The Cross
Virtual XI : The Clansman
This list contains all pre-reunion songs that were played two or more times during post-reunion tours.
As you can see, there's not a single No Prayer For The Dying song. In fact, only one NPFTD song was played on one post-reunion tour. I'll leave the answer as simple trivia for readers to find out
In fact, they do cover most of their career with their setlists. Why some songs are being overplayed while others from the same album/period are being neglected, that's a topic we already discussed numerous times here. The point is, no particular period is being neglected.
