When entertainer George Carl and singing group Harbor Lights performed at Theatre at the Center in Munster in October 2011, one performance wasn't enough.
The concert sold out, with box office staff promising waiting list names that Harbor Lights would return.
This weekend, the promise is fulfilled and Habor Lights is back in the musical spotlight for one concert tonight and one on Sunday.
"We entertain audiences of every age," said Carl, who helped create the group more than a decade ago.
"It's the music and and audience that matter most. We have a great time providing the type of music that brings people together."
Carl calls Harbor Lights concerts "a musical journey through the greatest hits from the Doo Wop era."
But it's also the a cappella renditions that surprise audiences the most. No band is necessary once the group's voice blend to form a seamless melody that leads to familiar tunes.
Ranging from "Under the Boardwalk" to "My Girl," Carl said the song selection "transports audiences back to a more simple, romantic time when life was far less complicated."
Harbor Lights are under the umbrella of the Collectables Recording Artists, the largest distributor of vintage music in the country.
Harbor Lights features five seasoned entertainers. In addition to Carl, there's Dave Mitchell, Cheryl De Rosier, Jimmy Calinski and "new kid" Fernando Rodriguez.
They have three albums, a trio of collected song favorites captures on CDs that have been internationally distributed: Almost Acappella, Absolutely Acappella and The Next Level.
Carl said each of the group members have impressive credentials, ranging from performances at The White House and the 100th Olympiad in Atlanta to live international broadcasts on Voice of America and tours in Europe to entertain US troops.
Carl said a Harbor Lights concert is never complete without including what's become a signature tune: "The Lion Sleeps Tonight."
"We make it a fun night, with lots of interaction with our audiences and shared memories. And we still get audiences who are surprised by the realization that there is no instrumental accompaniment."
He said this weekend's concerts will include renditions of songs from The Drifters, The Platters, The Coasters, The Diamonds, The Earls, The Skyliners, The Del Vikings, The Penguins, The Harptones, The Temptations, The Tokens, The 5 Satins, The Belmonts, The Ronettes and The Chantels.
"As we move through the show, Harbor Lights folds the history of the music into the presentation to invite the audience to become part of the show," Carl said.
"Our show features music that leaves the audience feeling happy to be part of a performance that is both past and present."
