The Entire Population of Hackney is the name used for a supergroup project featuring members of Iron Maiden, FM and Urchin that played two concerts in December 1985.

At the end of the World Slavery Tour in July 1985, Iron Maiden took six months off, when Nicko McBrain's frustration of not playing after winding down from an extensive Iron Maiden tour and looking at a six-month break, drove him to rent a rehearsal studio and invite Adrian Smith along to jam.

The audience recording called The Entire Population of Hackney was taken from the first show; Bruce Dickinson, Dave Murray and Steve Harris joined the band on stage only for the encores.

[3] Their set includes songs from all the members and some covers from Bob Seger and ZZ Top.
