The full show from 6/9 at Royal Arene is up on YouTube and the band sounds absolutely tremendous. I mean locked in like a machine. And Bruce sounds phenomenal this show.
Re Simon's intro on "Murders," I've heard it enough times to know its absolutely a deliberate choice. I'm used to it now. He's really settling in now and playing some really nice stuff.
Re backing tracks...I doubt it. There are parts played offstage by the keyboardist (I don't know if its still Michael Kenney, forgive me) but there are still enough flubs that tell me that's Maiden performs 100% live. Bruce having issues hearing while up on the platform behind the drums or Adrian's occasional frustrations where he'll stop playing til they get back in.
