I can tell you, from experience, that waiting 20 years to go to your first Maiden concert is everything you would hope it to be.
I've been a fan since SSOASS and saw Maiden live for the very first time two years ago.
When Bruce stopped I thought I was never going to see them live, because no chance in hell was I going to Blaze Bailey concert.
So when he returned I deceided that I would definitely go first chance I had. That chance was on the Somewhere Back in Time tour in 2008.
So I bought the ticket, practically framed it and on the 16th of August I took it of the wall and drove 3 hours -living in another dimension- to the best thing that ever happened to me.
I remember every step I took from the parking lot to the arena and back to my car after the concert was over. It was the most amazing experience ever.
On top of all that it turned out to become an epic concert with a lunar eclipse during Fear of the Dark.
Expect to be dreaming, but be sure to register every little bit of the entire evening. You are going to want to remember this for the rest of your life!
Oh, and pay attention!! I didn't for a second and missed giant Eddie
