Paul Day
Active: 1975–1976
Instruments: vocals
Release contributions: none
Day was the band's original lead vocalist but was the first to leave the group because according to Harris, "he didn't really have enough energy or charisma onstage."

Terry Rance
Active: 1975–1976
Instruments: guitars
Release contributions: none
As one of the band's original guitarists Rance disagreed on Murray's entrance in the band, taking it as a slight on his own ability.
To allow Murray to join Harris temporarily disbanded Iron Maiden in December 1976 and reformed the group soon afterwards without Rance or Dave Sullivan, the band's other original guitarist.

Dave Sullivan
Active: 1975–1976
Instruments: guitars
Release contributions: none
According to Sullivan himself, he "wasn't too bothered" with the prospect of Murray joining the group as he understood that "the lead sound was a bit lacking."
However along with Rance, Sullivan was not invited to rejoin Iron Maiden when they temporarily disbanded in 1976.

Ron Matthews
Active: 1975–1977
Instruments: drums
Release contributions: none
The band's original drummer Matthews states he was expelled from the band by their second vocalist, Wilcock.

Dennis Wilcock
Active: 1976–1978
Instruments: vocals
Release contributions: none
Wilcock replaced original vocalist Day and was the first to introduce special effects to the band's stage show, including fake blood capsules (placed in his mouth as he'd run a sword across his lips) and face paint.
Wilcock convinced Harris to sack most of the band including Murray following a row they had after a show at the Bridgehouse pub, Canning Town in 1977.
It was also claimed in The Early Days documentary that Wilcock disliked Murray's girlfriend.
Eventually, Wilcock decided he'd had enough with the group and left to form his own band, "V1".

Bob Sawyer (later Rob Angelo)
Active: 1977
Instruments: guitars
Release contributions: none
Sawyer (who would later go by the name of "Rob Angelo") would always try to upstage Murray, resulting in a confrontation with Harris (and expulsion from the group) after pretending to play guitar with his teeth when the audience could see that it was a trick.

Terry Wapram
Active: 1977–1978
Instruments: guitars
Release contributions: none
After Murray's dismissal from the group by Wilcock, Wapram was brought in as his replacement.
Having only played in Iron Maiden as the sole guitarist, Wapram was sacked after expressing that he was not content with Murray's reinstatement following Wilcock's departure.

Thunderstick (Barry Purkis)
Active: 1977
Instruments: drums
Release contributions: none
Thunderstick's stint in the band was left notoriously short, lasting just the one show at the Bridgehouse in 1977.
According to Harris, he performed poorly throughout the gig, including a particularly bad solo during which he shouted obscenities at the audience.
Thunderstick would later claim that his bad performance was caused by a row with his wife.

Tony Moore
Active: 1977
Instruments: keyboards
Release contributions: none
With both Murray and Sawyer expelled from the band, Harris decided to try a keyboardist.
After one show with Moore (the same played with Thunderstick on drums) Harris scrapped the idea.

Doug Sampson
Active: 1977–1979
Instruments: drums
Release contributions: The Soundhouse Tapes (1979 demo), BBC Archives (four songs from 1979)
Sampson first met Harris when they were both members of a band called Smiler in 1975.
When Harris formed Iron Maiden in December, Sampson was invited to join but refused deciding to leave music altogether, although he resumed drumming a short while later.
In November 1977, Sampson attended the band's only show with Thunderstick and, after a conversation with Harris that evening, he agreed to join the group.
Sampson remained with the band until they signed with EMI in 1979, after which he was dismissed on 22 December as he could not cope with the band's touring schedule.
