These two shows are both on tonight at tomorrow night at 9.05pm at The Space on Northbridge. They both have historical settings with modern jokes thrown in.
Upcastle downcastle centres around King Arthur, Lancelot and the holy grail. It is a pantomime for adults.
Liz is centred around Elizabeth 1 it is a comedy musical. It could easily work on a bigger scale, but it was good to be so close to a musical.
Having seen both, I would recommend seeing both. Go to both prepared for a little silliness.
