Eugenius! the Musical will end its second critically acclaimed run at The Other Palace - extended due to public demand - on Sunday 21 October and not now open the following week at the Ambassadors Theatre as planned.
Producer Kevin Wood revealed that a key investor had pulled out at the last minute due to the wider economic conditions.
"The past few days has been spent frantically trying to replace them but time has run out. In the New Year we will take stock and come again. We have spent too much time and money on this project to just let it die."
Eugenius!, with book music and lyrics by Ben Adams and Chris Wilkins, was due to run for a strictly limited 10-week season from Saturday 27 October 2018 - Saturday 5 January 2019.
Eugenius! has been nominated for 8 Off West End Awards including Best Musical, Best Male Performance in a Musical, Best Female Performance in a Musical, Lighting Design, Sound Design and Video Design.
