The Entire Population of Hackney is the name used for a project featuring members of Iron Maiden, FM and Urchin that played two concerts in 1985.
 It is also the name used for a bootleg recording of the first show.
 It is most notable for being the spark that would lead to Adrian Smith forming his ASAP project later on and ultimately his split with Iron Maiden in 1990 (He returned in 1999 and has since remained a member of the band, although he has pursued other projects).
 It is also notable for leading to the first Iron Maiden recording without the current lead singer on lead vocals.
Iron Maiden are an English heavy metal band formed by bassist Steve Harris in 1975.
 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.
 The Dickinson and Smith-penned "Flight of Icarus" was the first Iron Maiden single to chart in the United States, reaching number eight on the "Billboard" Mainstream Rock chart.
Paul Bruce Dickinson (born 7 August 1958), known professionally as Bruce Dickinson, is an English singer, songwriter, musician, airline pilot, entrepreneur, author and broadcaster.
 He is the lead singer of the heavy metal band Iron Maiden and is renowned for his wide-ranging operatic vocal style and energetic stage presence.
"Virus" is a single from Iron Maiden, released in 1996.
 It is the first single since 1980's "Women in Uniform" that does not appear on any official Iron Maiden studio album.
 It was, however, featured as a brand new track on the band's first ever career retrospective — 1996's double-disc "Best of the Beast".
 It is the only Iron Maiden song to be credited to both of the band's guitarists.
 It has never been performed live by Iron Maiden, but Blaze Bayley performed it several times in his solo career.
 Lyrically, the song warns of rising business corruption in an increasingly Internet-dependent world.
Iron Maiden are a British heavy metal band, founded in 1975 by bassist Steve Harris in London, England.
 After several personnel changes in the 1970s, the band settled on a lineup of Harris, Paul Di'Anno (lead vocals), Dave Murray (lead and rhythm guitars), Dennis Stratton (backing vocals, lead and rhythm guitar) and Clive Burr (drums), before they set out on their first professional tour, the Metal for Muthas Tour which supported the compilation album of the same name.
 After taking on a supporting slot with Judas Priest on their British Steel Tour and setting out on their own headline tour in support of their debut album, "Iron Maiden", the band supported Kiss on the European leg of their Unmasked Tour, following which Stratton was dismissed because of musical differences.
 Guitarist Adrian Smith was hired, following which Iron Maiden set out on a short series of UK dates before recording their second studio album, "Killers".
A Matter of Life and Death and A Matter of the Beast were two concert tours by Iron Maiden from 2006 to 2007.
 The first tour was unique, as the set list primarily consisted of the band's most recent release, "A Matter of Life and Death", in its entirety, although this got a mixed response from audiences.
 Unusually, the first leg didn't include "The Number of the Beast", a song which Iron Maiden had previously played on every tour since its inception.
 The second part of the tour, in celebration of "The Number of the Beast's" 25th anniversary, saw the band playing four songs from said album as well as five from "A Matter of Life and Death" (although they had initially planned to play five songs from both releases).
The Beast on the Road was a tour by the heavy metal band Iron Maiden, made in support of their album, "The Number of the Beast" in 1982.
 It is one of Iron Maiden's longest tours to date, only surpassed in length by the World Slavery Tour, comprising 187 dates in 18 countries taking place over 10 months.
Bruce Dickinson, a British heavy metal singer, has released six studio albums, two live albums, one compilations, ten singles, three video albums, fourteen music videos, and one box set.
 In 1979, after playing in local groups, Dickinson joined hard rock band Samson.
 He departed after two years to become Iron Maiden's lead vocalist.
 His debut with this band is considered a "masterpiece", which was followed with a series of top-ten releases.
 In 1989, while Iron Maiden were taking a year off, Dickinson and former Gillan guitarist, Janick Gers, composed a song for .
 His solo debut, "Tattooed Millionaire" (1990), was an effort that favoured a hard rock/pop metal approach, different from what fans assumed would be an aggressive, Iron Maiden-like album.
 Four songs—the title track, "Dive!
 Dive!
 Dive!
", "Born in '58", and a cover version of David Bowie's "All the Young Dudes"—were released as singles.
 Dickinson returned to Iron Maiden, accompanied by Gers as the new guitarist, and the project went on hiatus. "
Dive!
 Dive!
 Live!
" was a live video recorded from a concert in Los Angeles, California, in August 1990, and released in July 1991.
The Number of the Beast is the third studio album by the English heavy metal band Iron Maiden, released in March 1982.
 It was their first release to feature vocalist Bruce Dickinson and their last with the drummer Clive Burr.
Eddie Rips Up the World Tour was a concert tour by Iron Maiden in 2005 based on bringing back rarities from the first four Iron Maiden albums for the younger audience ("Iron Maiden", "Killers", "The Number of the Beast" and "Piece of Mind"), brought about by the band's 2004 DVD "".
