Hi - Clare here!
Here are a couple of documents you might find useful:
A PDF of The Barbican Gallery presentation:
The Pit Theatre plan (including the seating as it will be for the performance):
The other news is that I've just met with a Technical Theatre student, Rob, who is going to help out with Lighting for the event. He has already worked in the Pit which will be very helpful! He will be coming along to the morning session at the RCA on March 12th.
See you on Friday!
