Clue 1: A self-titled, multi-million selling debut album was released the same year as this Maiden track. This blockbuster album contains two Maiden song titles, but it's the more verbatim of them you're looking for.
Clue 2: The first two lines of the lyrics deal with introspection.
Clue 3: The song’s lyrics contain the name of a Beatles song - a song of theirs that has been widely broadcast.
Clue 4: The song has a single songwriter.
Clue 5: The lyrics feature the name of a political leader, an influential US rock band mainly active in the 1960’s, and also a long-standing environmental issue.
Clue 6: The song appears on more than one Maiden release. Even if it has a single songwriter (re: clue 4), a few of the lines in the song lyrics were added by another individual. Moreover, one could be forgiven for believing that a long-serving member of Maiden’s crew once took up vocal duties for a version of this song.
Not the ones: Wildest Dreams, 2 A.M, The Unbeliever, The Educated Fool, Wasting Love, No Prayer For The Dying, Infinite Dreams, Holy Smoke, Alexander the Great, Revelations
