Which of these musicians appeared on Iron Maiden's first studio album?

In December 1979, Steve Harris invited Dennis Stratton to join Iron Maiden after witnessing a Remus Down Boulevard performance. The band was also in need of a new drummer, and recruited Clive Burr on Stratton's recommendation. Stratton played on the group's first studio album, Iron Maiden, which was released in April 1980, and on the non-album single "Women in Uniform". Stratton also appeared in the home video recording "Live at the Ruskin" (recorded in 1980 and released in 2004 as part of "The History of Iron Maiden – Part 1: The Early Days" DVD set), and in the band's first British television appearance, when they performed "Running Free" on Top of the Pops. Stratton was with the band during their first European tour, supporting Kiss.
