FRANKLIN  — The Midtown Men — singing songs from the 1960s and featuring lush harmonies and a near-perfect blend of precision choreography with a dash of fun mixed in — performed a 90-minute set with no intermission on April 21 at the Smoky Mountain Center for the Performing Arts.

The high-energy vocal quartet and its stellar seven-piece band finished the regular show with a red-hot rendition of  The Four Seasons’ classic, “November 1963 (Oh, What a Night).” 

With the crowd cheering and on its feet, the four singers began walking off the stage at the conclusion of the show’s finale, but suddenly swiveled on their toes simultaneously and returned for one rousing encore — Frankie Valli and the Four Seasons’ “Bye, Bye, Baby (Baby Goodbye),” waving farewell to the near-ecstatic crowd as part of the choreography.

About 700 people attended the concert, which marked the second visit locally by the Midtown Men, a group that made its Franklin debut about six years ago.

The group’s vocalists were introduced as “four stars from the original cast of Broadway’s (musical) ‘The Jersey Boys.’” They included Michael Longoria, Christian Hoff, Daniel Reichard and J. Robert Spencer. It was Longoria who played — and sang — the part of Valli in “Jersey Boys,” a Tony Award-winner. 

His ability to hit the high notes that Valli did was nothing short of amazing, although sometimes he sounded  less like the silky-smooth-voiced Valli and more like Donald Duck.

While the choreography, vocal harmony and backing band’s musical punch were the strong points of the show, the weak point was that the Midtown Men seemed to lack a true lead singer, especially when Longoria was not singing Valli-Four Seasons songs. The others have fine voices, especially for backup vocals, but nobody really stood out.

As it was Hoff’s 50th birthday, the group led the crowd in singing happy birthday to him — and a birthday cake and a group of doughnuts, both lighted up with candles, were carried onto the stage, with Hoff successfully blowing out all of the candles.

The Midtown Men’s backing band include a guitarist, bassist, drummer, a three-member horn section (trombonist, trumpeter and saxophonist) and a keyboardist.

The vocalists were dressed in black, including sequined tuxedos that sparkled, and accented by bright-red pocket squares. The band members simply wore all-black.

The show opened with The Four Seasons’ mega-hit “Sherry,” 

In noting that the April 21 show marked the group’s second appearance at the SMCPA, one of the vocalists said, “It is good to be back here.” He praised the area’s scenic beauty and its friendly residents.

In a reference to the musical “Jersey Boys,” he noted that “our story began on 42nd Street on Broadway. We were the original cast of ‘The Jersey Boys’ and, something happened, and we fell in love with ‘60s music” and the quartet went on to form the Midtown Men.

“We’ve done over 800 concerts” in the eight-year history of the group, he said, adding that many of the songs the Midtown Men would be performing at the Franklin show “are about love.” He then emphasized that “we need more love in the world” right now.

The group then sang Jackie DeShannon’s “Put a Little Love in Your Heart,” followed by The Turtles’ “Happy Together,” Marvin Gaye’s “Ain’t That Peculiar” and the Beach Boys’ “Wouldn’t It Be Nice?” 

After celebrating Hoff’s 50th birthday on stage briefly, the group — for the first time in the show — sat on stools, as Hoff sang his best lead of the night on the Lovin’ Spoonful’s “What a Day for a Daydream,” followed by the Youngbloods’ “Get Together,” Van Morrison’s “MoonDance” and the Ronettes’ “Be My Baby.” 

Back on their feet and showing off their dazzling choreography, the Midtown Men then performed a rousing rendition of the Beatles’ “Got to Get You Into My Life.”

At that point, the vocalists told of meeting their real-life counterparts in the Four Seasons that each of them played in “Jersey Boys” — and heaped praise on them. 

The Midtown Men then performed a medley of Four Seasons songs from “Jersey Boys,” which, a member noted, “we got to do eight times per week,” when they were with the show.

The medley, which sparked one of the loudest and most enthusiastic responses of the night from the audience, included “Working My Way Back to You,” “Big Girls Don’t Cry,” “Big Man in Town,” “Rag Doll” and finished with a bang with “Walk Like a Man,” with hilarious choreography that included the vocalists taking hilariously steps that exageratedly emphasized their manliness.

As the quartet left the stage for a brief costume change, the band kept the audience in the ‘60s mood, playing instrumentals of “Secret Agent Man,” “Theme From the Pink Panther,” “Theme From the Munsters” and “Theme from Hawaii 5-0.”

Then, the quartet returned to the stage in the same all-black outfits, but with the addition of  bright-red tuxedo jackets and launched enthusiastically into the Temptations’ “Get Ready,” which was interesting to hear with Langoria singing lead Valli-style.

After that, the group performed renditions of the Rascals’ “Good Lovin’” the Zombies’ “Time of the Season” the Monkees’ “I’m Not Your Stepping Stone” and the Rascals “Groovin’” — all of which were true highlights of the concert. The audience’s sustained applause seemed to confirm my evaluation. Only the earlier Four Seasons’ medley was comparable.

The hard-working quartet then slowed the pace, as the vocalists sat on side-by-side stools to sing some more mellow songs of the night, with Hoff singing a deliciously haunting and jazzy version of Buffalo Springfield’s “For What It’s Worth.”

Still on stools, the group sang Glenn Campbell’s memorable ballad, “Galveston”

Back on their feet, Langoria began the lead vocals on Valli’s “My Eyes Adored You,”after which each of the other quartet members sang lead on a verse, too, for an interesting effect.

Then Langoria, with an obvious touch of pride, told the crowd that the next song was “my big number” in “Jersey Boys” — as he launched into the lead of “Can’t Take My Eyes Off  You.” The audience then applauded Langoria’s efforts enthusiastically.

After the show’s finale and the encore, the crowd cheered and the smiling (and sweating) Midtown Men gathered side-by-side at the front of the stage with arms around one another and performed an elegant group bow — and then exited permanently for the night.
