For fans of that purebred strain of vocal soul known as Doo Wop, it’s become almost as much of a cause for discussion as keeping track of group personnel changes, recording dates, and other true-fan trivia. We’re talking here about the situation in which two or more competing groups each lay claim to the name of some classic hitmaking act — whether through the presence of a onetime member or by virtue of rights held by an outside party or promoter. It’s a sticking point that’s too often played out around courtrooms and conference tables, rather than on a battle-of-the-bands stage, where such matters might be more effectively resolved.

When the virtuoso voices transform Middletown Arts Center into an old-neighborhood hangout this Saturday night, the promoters (Coll Productions, teaming with Street Corner Sounds Society) will be spinning this record-hop in a way designed to put aside any “imposter band” acrimony — as A Tribute to Our Doo Wop Legends, in which a collection of veteran regional acts each pay harmonious homage to an earlier golden-age group who inspired them.

Toplining the 7 p.m. show is an act that can trace a genuine pedigree back to one of the pioneer groups of rock and roll’s formative years. As the offspring of lead singer Norman Wright — whose Del Vikings helped define the whole genre with their smash hit “Come Go With Me” — Anthony and Norman Wright Jr. have kept the family business swinging, performing officially as the Del Vikings, and on this occasion as Come Go With Me: A Tribute to the Sound of the Del Vikings.

They’ll be joined on the MAC bandstand by Blue Velvet, a group that’s made a specialty of saluting the smooth sounds of the Moonglows (“Sincerely,” “Ten Commandments of Love”) — as well as Sky’s the Limit, here delivering a tribute to “You Belong to Me” and other signature songs by the Duprees (themselves frequent visitors to venues in and around the Greater Red Bank Green).

A favorite on the region’s rejuvenated a cappella circuit, Re-member Then performs a special “without a net” set devoted to the Bronx-bred originals the Earls — while fellow a cappella aces Grand Central Echoes honor the two New York City bands whose legendary street-corner singing battles inspired one of the best-regarded doo wop albums of all time, The Paragons Meet The Jesters.

“Sally G” of the Street Corner Sounds Society emcees the concert, preceded at 5:30 by a special pre-show reception featuring a buffet Italian dinner. Reserve tickets ($37.95 for reception and show) by calling (732) 706-4100.
