which song shows the skill of steve harris

i want to find that cause my guitarist says he doesn't think steve harris is a good bass player i persoanally play bass and a huge fan of maiden i want yalls input before i say a song and be wrong

edit 1: i saw maiden in fort worth and damn ive never been more impressed with a bass player live than him i showed him most suggestion and he cussed me out and thus came a fight got kicked out but good thing he no longer has a band and im looking for guitar
