The band's first album, 1980's "Iron Maiden", was written primarily by Harris, with vocalist Paul Di'Anno co-writing two tracks and guitarist Dave Murray contributing "Charlotte the Harlot".  The 1981 follow-up, "Killers", was written almost entirely by the bassist, with frontman Di'Anno contributing only to the title track, "Killers" (the North American bonus track "Twilight Zone" was credited to Harris and Murray).  Bruce Dickinson replaced Di'Anno after the release of "Killers", although he did not contribute any songwriting to "The Number of the Beast", released in 1982, which featured three songs co-written by guitarist Adrian Smith.  "The Number of the Beast" also spawned Iron Maiden's first UK Singles Chart top ten in the form of "Run to the Hills", which charted at number seven on its release.  It was not until 1983's "Piece of Mind" that the songwriting process became a more varied and collaborative approach, with just four of its nine tracks being credited solely to Harris, two to Dickinson and Smith, one to Harris and Murray, one to Dickinson alone, and one to Harris, Dickinson, and Smith.

It is the first tour to feature Janick Gers, who replaced leaving guitarist Adrian Smith.  Following their large-scale stage shows used in the 1980s, the band opted for a less elaborate production from this tour onwards, with bassist Steve Harris commenting, "We thought the "Seventh Son" ... stage show just got a bit out of hand.  I mean, the actual Eddie and the backdrops I thought looked amazing, but the giant icebergs and stuff were a bit naff, I think, and we just wanted to get away from all that and turn everything into like a massive club gig again, which we really managed to do.  And having Janick in the band gave everybody a much-needed kick up the arse, too, because, being new, he was so enthusiastic about everything.  I think it made us all open our eyes a bit and look at things in a new way."
