Well, it's late so it's going to be a short blog :D! The song is Iron Maiden by Iron Maiden! Everytime they play the song live, it sounds different! Here are two of my favorite perfomances:

Iron Maiden, Iron Maiden - 1 (1999, NYC)

Iron Maiden, Iron Maiden - 2 (live after death)

I hope you liked them! This is the song where Eddie comes out a lot :)!
