Well, I don't know. But the orchestral tours SMB and NB to date haven't been recorded with this in mind so I imagine not. My guess is that the mixing of the orchestra quickly and accurately and warmly is a stumbling block, perhaps? Each show is mixed quickly for the official bootlegs and it's much easier to quickly mix a 5 or 6 piece band than 46?
Having said that, a monitor or desk mix would do, so maybe the deal's not right

Well, I hope I'm wrong and some come out, but im pretty sure it won't happen, especially as New Blood hasn't yet hit the streets.
