For some reason despite its classic status, it was the very last song to hook me on the album, and never really transcended into an all-time great. I remember when I was 13 or so showing off my autistic knowledge of the Iron Maiden discography's track order including track durations when possible, I had this weird moment where I was like "Hmm, I swear this album had 9 tracks instead of 8 like the rest of the early Bruce albums, but I can't remember that 9th, oh well", and The Trooper was the one I couldn't remember.
