I came across two interesting clips of Sunday's show in Córdoba:
1.

During "The Book Of Souls", Eddie falls onstage, and the roadies help him stand up! I guess his age is really starting to show
(you can even see Steve noticing it, and constantly checking out if Eddie is OK.)

https://www.youtube.com/watch?v=t7kdNY6C2qw. This is a short clip by InYourFace TV (a website from Córdoba).
They interviewed some fans right before the concert. The video also features some (raw) footage of the bands onstage (Anthrax at 2:41, Maiden at 3:20).
I come back from work at 9pm, around the time Maiden goes on stage. If I find something (maybe a live broadcast?) I'll post it.
EDIT: Just found these links:
