It's late, so I won't say much, but I did want to congratulate BRB's technical team on managing to transfer their production of Nutcracker to the barn O2 so well. It looked very good. I haven't seen it for over a decade, so I'll leave it to Janet and others with more recent experience to say if anything has changed.
Some practicalities: with a late start and I suspect a longer interval than intended, it finished at just after 10 pm. The orchestra non-pit is in front of the stage, so nobody will be very close, and I think some people might have the harps in their line of sight quite badly.
