Iron Maiden had a strict and organised routine that suited the band's writing style, which Dickinson described as a "time table". After a few gigs, they began writing new material for their third album, "The Number of the Beast", released in 1982. In the wake of Samson's contractual problems, Dickinson could not legally be credited on any of the record's songs, having to make, what he called, a "moral contribution", later revealing that he had contributed to "The Prisoner", "Children of the Damned" and "Run to the Hills". In the documentary "12 Wasted Years", manager Rod Smallwood refers to "The Prisoner" as being co-written by Dickinson and Adrian Smith. The album was a major success, topping the British charts, and earning platinum status in the UK and the US. Following the release, the band embarked on a supporting tour around the globe.
