Teaming up with not-for-profit organisation Water.org, the event will celebrate the start of Urinetown's long-term support for this real and pressing issue that the world's population is currently facing.

Urinetown transferred to the Apollo Theatre, Shaftesbury Avenue on 29th September 2014 and encompasses an impressive line up of talented performers including Olivier Award-winner Jenna Russell, Jonathan Slinger, Eastenders' Marc Elliot, and actor and playwright Simon Paisley Day.

Urinetown is a satorical and futuristic musical which is set during a time when the world's water supply has been depleted. Consequently, the use of private toilets has been banned and anyone caught committing such an offense face being sent to Urinetown.

Director Jamie Lloyd explains more about its collaboration with charity Water.org "The best sort of theatre engages directly with the world. It may be great fun, but it should also be vital and apposite, and perhaps, instigate a broader discussion. Urinetown's dystopian future does not have to be a prediction unless we make it so. We are delighted that the production can assist the mission of Water.org whilst keeping its audience laughing along the way".

780 million people in the world lack access to safe water and 2.5 billion lack improved sanitation. Even more alarmingly, figures show that more people have access to a mobile phone than a toilet. Water.org has transformed the lives of more than a million individuals around the word, ensuring a better community and life for generations ahead. Co-founder of Water.org, Matt Damon says "Water.org welcomes Urinetown's support to share our vision of the world where everyone has access to safe drinking water and can experience dignity of a toilet".

Gala tickets can be purchased through the website www.urinetown.co.uk and are priced from £29.50. Premium tickets are also available at £125, which includes VIP seating in the stalls and dress circle, and access to a post-performance gala reception with the cast.
