You’ve heard of residencies in Las Vegas whereby a pop music star headlines a concert for an extended engagement at one venue. Think Celine Dion, Elton John and Jennifer Lopez. And don’t forget Liberace at the Riviera Hotel and Casino in the 1940s and Frank Sinatra and the Rat Pack at the Sands Hotel and Casino in the 1950s.

“Leader of the Pack: The Ellie Greenwich Musical,” with songs definitive of the 1960s, and though not billed as such is in residency through July 20, Bucks County Playhouse, New Hope.

The June 21 opening night performance was seen for this review.

“Leader of the Pack” shares a pedigree with Vegas residencies: It’s dynamic, fast-paced and glitzy. When the backup female and male singers kick up their heels, and the orchestra is in full-swing and the stage lights flash, the legendary Bucks County Playhouse is transformed into a Las Vegas Strip showroom. Call it “Vegas on The Delaware.”

Before self-contained songwriting wunderkinds such as The Beach Boys and The Beatles, pop-rock groups and vocalists looked to songwriters for hits.

Some songwriters escaped the confines of New York’s Brill Building piano cubicles to skyrocket to headliner fame, notably Carole King and Neil Sedaka.

You may not readily know the name Ellie Greenwich, who cowrote songs with her husband Jeff Barry, along with George “Shadow” Morton and others. You will know their hits, often by so-called girl groups, including: “Be My Baby,” “Baby, I Love You,” “I Can Hear Music,” The Ronettes; “Da Doo Ron Ron,” “Then He Kissed Me,” The Crystals; “Chapel of Love,” The Dixie Cups; “River Deep, Mountain High,” Ike & Tina Turner; “Do-Wah-Diddy Diddy,” The Exciters, Manfred Mann; “Hanky Panky,” Tommy James & the Shondells; “Leader of the Pack,” the Shangri-Las, and “Christmas (Baby Please Come Home),” Darlene Love.

“Leader of the Pack: The Ellie Greenwich Musical” includes these among some 13 chart-toppers for a total of some 25 songs in a foot-stompin,’ finger-snappin’ and memory-stirring musical that is absolutely exhilarating. This is not a jukebox musical. This is a record-store musical. The show is nothing less than a treasure trove of transistor-radio under the covers, Saturday night town hall record hops and car radio main street cruising (and dirt road parking) good-time nostalgia for Baby Boomers.

According to the Songwriters Hall of Fame, Ellie Greenwich (1949-2009) was one of the most successful songwriters of pop music and a major influence on 1960s rock ‘n’ roll.

With “Leader of the Pack: The Ellie Greenwich Musical,” she gets her due. The musical, with music and lyrics by Ellie Greenwich and friends, and Liner Notes (Book) by Anne Beatts, is not all lollipops and moon beams.

Greenwich, born in Brooklyn (and winning first place in a newspaper poetry contest) to parents of Russian descent, a Catholic father and Jewish mother, moved at age 11 with her family to Levittown, Long Island, N.Y., and received a BA with high honors in English from Hofstra University, where she met Jeff Barry. She formed a girls group, The Jivettes.

“Leader of the Pack: The Ellie Greenwich Musical” would be more than enough entertainment for the songs alone. The musical does something more: It conveys the abundant creativity, enthusiastic stick-to-itiveness and cosmic loneliness and personal insecurities that were the heart and soul of her music.

Kyra Kennedy as Ellie Greenwich conveys the confident exuberance and the moments of self-doubt that went hand-in-hand in the singer-songwriter’s persona. Kennedy has a warm, deep and resonant voice that rocks out confidently on “And Then He Kissed Me” and expresses a heart-wrenching vulnerability on “Rock of Rages” and “What A Guy.”

The Bucks’ production has a bevy of great vocalists, including Galyana Castillo (Darlene Love), who has the show’s showstopper, “Christmas (Baby Please Come Home)”; Giuliana Augello (Annie Golden) on the Phil Spector-produced “Wall of Sound” classic, “Be My Baby,” and Jenny Lee Stern (Rosie, Lounge Singer), “Why Do Lovers Break Each Other’s Hearts?”

Not to be outdone is Michael Evan Williams (Jeff Barry) on “Do-Wah-Diddy Diddy.”

The show’s choreography by Shea Sullivan, who directs the show with a sure hand for frivolity, excitement and quiet reflection, is spectacular. Fiona Claire-Huber and David Nick Alea are absolutely breathtaking as the Dance Couple.

The talented and memorable cast of 19 includes Danny Rutigliano (Gus Sharkey), Sy Chounchaisit (Pattie) and LaRaisha DiEvelyn Dionne (Jasmine Guy).

The phenomenal leggy and high-stepping ensemble includes DeShawn Travis Bowens, Halley Daigle-Saez, Elena Doyno, Sofia Douvikas, Fabi Gallmeister, John Michael Peterson, Lexie Plath, Ethan Eisaiah Rualo and Elizabeth Yanick.

The Bucks’ production is top-notch, with each performer giving his, her or their all, and totally professional in every department.

The 10-piece orchestra, which is placed on a catwalk high above the stage, is superb and continually propels the show. Music Director is Eric Alsford. Sound Design is by Jeff Sherwood.

Scenic Design by Charlie Corcoran and Lighting Design by Kirk Bookman create a variety of settings, from residence interior to recording studio to nightclub.

The costumes, by turns spectacular and true to the era, are by Costume Designer Chadd McMillan. Hair, Wig & Makeup Design is by J. Jared Janas.

The show, which runs about 90 minutes with no intermission, concludes with “River Deep, Mountain High” by the Full Company, bringing the sold-out audience to its feet to dance at their seats.

Ellie Greenwich is indeed the “Leader of the Pack” of 1960s’ romance and relationships. If you remember the songs, the times and the sentiments, don’t miss “Leader of the Pack: The Ellie Greenwich Musical.” And if you weren’t there, see what you missed.
