The new Rockettes show has been postponed until next year.
"Heart and Lights" featuring the legendary Rockettes was set to open next week at Radio City Music Hall, but MSG Entertainment says it is not ready for the stage yet.
The technologically ambitious show will now open in 2015, but no exact dates have been announced.
A spokesperson says that the music and story needed to be tweaked, and the upcoming NFL draft at Radio was cutting into rehearsal time.
MSG Entertainment says it sold more than 100,000 tickets and that refunds will be available to all ticketholders.
