Iron Maiden: Flight 666 is a 2009 British/Canadian documentary film featuring the heavy metal band Iron Maiden. The film follows the band on the first leg of their Somewhere Back in Time World Tour between February and March 2008.
"Revelations" is one of the few Maiden songs written solely by Bruce Dickinson. On earlier live performances of the song, Dickinson played rhythm guitar on one section that required a dual lead performed by Dave Murray and Adrian Smith. In more recent performances such as Eddie Rips Up The World Tour and Somewhere Back In Time World Tour, the rhythm guitar section was performed by Janick Gers, giving Dickinson more freedom around the stage. The lyrics are based partly on a book by Aleister Crowley, but this is also juxtaposed with a verse taken from a hymn by G. K. Chesterton, which forms the first verse of the song
