Here is my take on the iconic Iron Maiden “The Trooper” single album cover set to a Pittsburgh Steeler Theme. Go Steelers! “The Trooper” was Iron Maiden’s ninth single, released on 20 June 1983, and the second from their 1983 album Piece of Mind. It was one of only a few songs to get much radio airplay in the US, thus peaking at No. 28 on the US Mainstream Rock charts.
