If you shoot a stand-alone show for DVD though then you're gonna have to overcome the issue of being rusty because you haven't played that set before or haven't played at all recently.

Rob screamed his throat out onstage all throughout the seventies and eighties which was awesome at the time, but the long term damage he caused is more or less irreparable now.
I don't disagree that Bruce sounds great now but back in the day his voice ranged from pretty good to totally shot between the World Slavery tour and the time he left Maiden. He recovered marvelously in the mid-90's but during their heyday Maiden was touring so much that it seemed to have torn him up pretty good.
