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.
