That would be incredible dull, given that they played those songs to death starting with the Somewhere Back In Time Tour.
If they won't redeem themselves by reviving long forgotten gems from the 80s like Killers, 22 Acacia Avenue, Flight of Icarus, Die With Your Boots On, Still Life, To Tame A Land, Sea of Madness, Stranger In A Strange Land or Infinite Dreams, this tour will be pointless in my opinion.
"The concept for the Legacy Of The Beast World Tour was inspired by Maiden’s mobile game and comic book of the same name and the stage set design will feature a number of different but interlocking “worlds” with a set list covering a large selection of Eighties material with a handful of surprises from later albums to add diversity."
What do you think that means? Will they have different themes? Maybe underworld theme for some songs, battlefield for some songs etc.
