Question: When was the vocalist that took over Bruce Dickinson's position as the lead vocalist for Iron Maiden born? 
Context: Wolfsbane was the 1994 third eponymous album from British heavy metal band Wolfsbane.  Not long after the album's release, vocalist Blaze Bayley took over Bruce Dickinson's position as the lead vocalist for Iron Maiden.  It would end up becoming Wolfsbane's final studio album before their 16-year breakup from 1994 to 2010. Tyranny of Souls is a heavy metal album released by Iron Maiden vocalist Bruce Dickinson on 23 May 2005.  The cover art is a work by renaissance artist Hans Memling.  It is his first solo album since rejoining Iron Maiden in 1999 and his most recent studio album as a solo artist. 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. The Book of Souls World Tour was a concert tour by Iron Maiden, held in support of their sixteenth studio album, "The Book of Souls".  The first leg of the tour saw the band play shows in 36 countries across six continents, which included their debut performances in El Salvador, Lithuania and China.  With 117 shows, it was the longest tour with Bruce Dickinson on vocals since the "Somewhere on Tour" in 1986-87.  The group, their crew and equipment were transported on a customised Boeing 747-400, nicknamed "Ed Force One", which was piloted by vocalist Bruce Dickinson. The Virtual XI Tour was a concert tour by the heavy metal band Iron Maiden from 22 April 1998 to 12 December 1998.  As with their previous tour, several of the band's U.S. shows had to be cancelled after vocalist Blaze Bayley had issues with his voice, this time reportedly from an allergic reaction to pollen and dust while the group were in Nevada and Arizona.  The band later made up the Los Angeles and San Diego dates.  This would be Iron Maiden's last tour with Bayley as then former vocalist Bruce Dickinson would return to the group the following year. Samson were a British hard rock band formed in 1977 by guitarist and vocalist Paul Samson.

Drummer Clive Burr was also a member of the band, both before and after his tenure with Iron Maiden.  Drummer Mel Gaynor had a successful music career being a member of Simple Minds for over 20 years.  Dickinson's replacement on vocals, Nicky Moore, performed with Samson throughout the mid-1980s and again from the late 1990s onwards; he has also been a member of the bands Mammoth and Nicky Moore and the Blues Corporation.

It was co-produced by Kevin Shirley and Harris.  The title is inspired by the British cult film of the same name.
