This was the band's first world tour, including their debut shows in North America (where they supported Judas Priest on their World Wide Blitz Tour and UFO on select dates)[1] and Japan where they recorded the live release, Maiden Japan.

[2] On top of this, the band moved into larger venues in the United Kingdom, including the Hammersmith Odeon, in London.

[3] This would be Iron Maiden's last tour with singer Paul Di'Anno, who was dismissed due to his unreliability.

[4] He was replaced by Samson vocalist Bruce Dickinson, with whom the band undertook a short series of concerts in Italy and the UK before they set about writing and recording their next album, The Number of the Beast.

"[9] On the other hand, Steve Harris, the band's bassist, has since said that he did not "know whether he was seeking attention or what", arguing that having to cancel shows because of personal problems was intolerable[4] and ultimately cemented Di'Anno's dismissal.
