Sorry this has been even more boring than usual for a while. Many things are afoot. I have nearly written a short novel, for instance.
If you are coming the Mighty Fin Christmas Show - and I hope you are - then the lovely Network Theatre is incredibly convenient for Waterloo. However, it is a little tricky to find. You head out the side door near the Jubilee Line escalators and turn right towards the Old Vic. Almost immediately, there is an unpromising looking access road on your right called Lower Road. You head down this, into the bowels of the station, past bins and a security gate where you may have to present your e-ticket.
DO NOT BE DISCOURAGED.
Keep your eye out for the small door to the theatre on your left. There is a map and also a video here.
I hope you enjoy it,
