Unless they are around the back - I guess there is a room within the theatre that a 'flyaway' gallery can be placed into, rather than having an OBU parked up for 8 weeks?
It's about as funny as a broken neck, and the use of the screens in the background looks very odd to me. It's like in the 70s when news programmes discovered chroma key and would fill the background with a photo. About the right era of humour too.
