More than 30 years after the musical “Harmony” was written, it is finally preparing to make its Broadway debut. The show was almost lost to history — like its subject.

The historical show written by Barry Manilow and Bruce Sussman tells the true story of the forgotten German performing group The Comedian Harmonists. Many regard the six-man group as one of the first boy bands, as they recorded a string of popular albums and played sold-out venues around the globe.

But at the height of its popularity, the Nazi party took control of Germany, and the members were denounced for being degenerates. Three of the group’s members were Jewish, and possessing its music was considered a crime.

Relegated to obscurity and word of mouth, Sussman learned of the group through a documentary.

“I had never heard of them. And I thought, (Manilow) knows every song ever written. He knows every group that ever was,” Sussman said.

Manilow was also unaware. “Then we realized that’s the story,” Sussman said.

But that was half the battle, as information on the group was hard to come by. “The Nazis tried to annihilate them, and they did. You couldn’t find any records. You couldn’t look at any of their movies,” Manilow said.

While performing in Germany, Manilow visited a record store in Berlin to check out a major display.

“There was a whole wall of Comedian Harmonists. It was like the Beatles. They were the Beatles. They were the Backstreet Boys. They were the first boy band. That’s how big they were,” Manilow said.

While the show was written in the 1990s, Manilow states the long road to Broadway had little to do with finishing the show and more about finding the right person to bring it to the big stage.

“Basically, it was ‘Harmony’ even in 1997. Great reviews. Everybody loved it. And it wasn’t about the show, it was about the producers just couldn’t keep going,” Manilow said.

Then Tony-winning producer Ken Davenport stepped in. “He delivered all the way,” Sussman said. Previews begin Oct. 18 at the Barrymore Theatre.

The musical stars Sierra Boggess, Chip Zien and Julie Benko. The six Comedian Harmonists are Sean Bell, Danny Kornfeld, Zal Owen, Eric Peters, Blake Roman and Steven Telsey. The director is Warren Carlyle.

Golding, Lo welcome second child: Henry Golding and his wife, Liv Lo, announced the arrival of their second daughter, a month after she was born.

The couple announced the baby news in a shared Instagram post Tuesday. The clip, set to Chelsea Cutler’s “Your Bones,” shows Lo in the delivery room holding the newborn and a teary Golding cutting the umbilical cord.

The post included clips of Lo crying and baby Florence in a NICU incubator. “The journey of childbirth is full of its ups and downs, but glorious none the other,” the caption read.
