As previously announced Thoroughly Modern Millie was to play London fringe venue Theatro Technis this October.
The production has now been postponed to April 2015 due to illness in the family of director Drew Baker.
A spokesman for the producers, Entourage Productions, said, “regrettably, director Drew Baker is unable to direct the show at this time due to the serious illness of a family member.
"This production has been a long time in the making. Entourage are very excited by Drew’s vision of the show and the cast and team we have assembled.
"Postponing it will allow us to bring that vision to the stage with the full company we already have in place, subject to their availability."
Russell Grant had been cast as Mrs Meers and Molly Marie Walsh had been cast in the title role.
Tickets are being refunded and booking will open soon for the new dates.
