I simply don't understand it - but each to their own I guess.
If it's a band playing a small venue (say, 500 people or so) two nights in a row, and you meet them both times afterwards for a chat and a drink, I get that - but (current)* Maiden?
[*If I had the opportunity to see them in London in the 70s then yes, for sure, but now?]
Seriously, I'm not trying to start an argument or something but really trying to understand - how can you guys go and see the same set with mostly the same witticisms from BD again and again, and, more importantly, genuinely enjoy it?
