The original line-up was short-lived, with vocalist Paul Day being the first casualty as, according to Harris, he lacked "energy or charisma on stage". He was replaced by Dennis Wilcock, a Kiss fan who used make-up and fake blood during live performances. Wilcock's friend, Dave Murray, was invited to join, much to the dismay of the band's guitarists Dave Sullivan and Terry Rance. Their frustration led Harris to temporarily disband Iron Maiden in 1976, though the group reformed soon after with Murray as the sole guitarist. Harris and Murray remain the band's longest-standing members and have performed on all of their releases.
