Paul Di'Anno began his professional musical career singing with <a href="http://www.last.fm/music/Iron+Maiden" class="bbcode_artist">Iron Maiden</a> in 1978. His style has been described as more punk-influenced than Iron Maiden's following vocalist Bruce Dickinson. Di'Anno left the band after two albums, the reasons for so vary between sources; either leaving by his own will or being sacked due to excessive drug and drinking habits with a conflicting personality .
