Considered one of the most successful heavy metal bands in history, Iron Maiden has sold over 85 million records worldwide with little radio or television support. The band won the Ivor Novello Award for international achievement in 2002, and were also inducted into the Hollywood RockWalk in Sunset Boulevard, Los Angeles, California during their United States tour in 2005.

As of October 2013, the band have played over 2000 live shows throughout their career. For the past 35 years, the band have been supported by their famous mascot, “Eddie”, who has appeared on almost all of their album and single covers, as well as in their live shows.
Di’Anno grew up in Chingford, England — spending his teenage years singing in various rock bands and working as a butcher and chef. He became the band’s singer after the departure of the very unpredictable Dennis Wilcock, who had pressured Iron Maiden founder and bassist Steve Harris into firing every member of the band (including Dave Murray), before becoming fed up himself. According to Iron Maiden’s The Early Days DVD, he was introduced to the band by drummer Doug Sampson, an old friend of Harris’ from his days in the band ‘Smiler’. It was around this time that he first adopted the stage name Di’Anno, which he would later use to claim Italian descent. In 1981, Di’Anno left Iron Maiden after a meeting with the band and their manager Rod Smallwood.
