Iron Maiden just played Alexander The Great live for the first time ever. But there are still 48 Maiden songs that have never been given an airing

That list until recently (2023) included my personal favorite Alexander The Great off of the Somewhere In Time Album. It took them almost 40 years to play it live.
Here it is live in 2023. It's pretty awesome and Bruce still has the pipes.
