There was a film called Up n' Under in the 90s satrring Gary Olsen, Samantha Janus and Neil Morrisey and looking at the description of the play on the website it seems to be the same thing more or less.

The film was based on the Godber play.

I distinctly remember Samantha Janus showing everything in a shower scene in that film. Never had any players in the shower block like that when I played!

It was a very nice sight as well.

You won't get to see Samantha's Janus, but it'll be a great show - a good friend of mine is a Tiny House performer and having been a jr and open age RL player and a lifelong WTW supporter (don't hold that against him) he's playing this one with a lot of truths from his own experiences in the amateur game.

It'll be great fun - I'd recommend it.
