The musical about the life of the late rocker John Lennon will now open Aug. 14 at New York's Broadhurst Theatre, Playbill On-Line reported.
In announcing the delay, producer Allan McKeon said he wanted to give writer-director Don Scardino and the creative team "the opportunity to make adjustments to the show," Playbill said.
Scardino was asked to make "fundamental changes" in the opening and closing scenes, McKeown said. Another song from vast Lennon catalog will also be added.
The show has been described as a "musical biography, a concert, and a celebration all in one."
