He did play Silicon Messiah.
I haven't heard Blood & Belief before though, it might be there are tracks I'd like more than the Maiden ones. But it's just a matter of taste mostly; as good as Bruce and Blaze are with their solo careers, I still like Maiden in general more.
As for Sign of the Cross, that's something I wouldn't like Blaze to play. It's got relatively little singing and about 6 minutes of instrumental, so I would rather see Maiden originally play it.
Edit:
Here's a video of the Clansman from the gig, pretty good quality and you can see Blaze well. Like I said, he's got almost as much energy as Bruce at the best of times. Damn, I would sell my soul to see Bruce in a club gig.
