The production, with a book by Andrew Bergman and music and lyrics by Jason Robert Brown, is based on the movie of the same name. (The witty Bergman also did the screenplay of the original.) The new musical had its premiere at the Paper Mill Playhouse in Millburn, N.J., and fortunately has made its way to Broadway.

As in the case of many a musical, the story is corny, but the basic idea is fleshed out with inventiveness, amusing characterizations expertly interpreted and belly-laugh comedy. A large orchestra provides musical kick, Denis Jones’s choreography captures the aura of Vegas, Gary Griffin’s direction keeps everything moving swiftly for most of the time and Anna Louizos gets high marks for her scenic and projection design.

Rob McLure is immensely enjoyable as Jack Singer, an affable Brooklyn shmo who croons “I Love Betsy” to express his affection for his girlfriend, Betsy Nolan, played with spirit by knockout Brynn O’Malley. The trouble is that after a five-year relationship he still can’t bring himself to the altar, and her patience is wearing thin. The trouble is that the wish of his dying mother was that he never marry, as no woman could match the love of his mom, who puts a curse on any woman who would ensnare her son. There is a hilarious death bed seen with the overbearing mom played by very funny Nany Opel, who also turns up in memory at various points in the convoluted plot.

Finally, Jack agrees to go to Las Vegas and get married, but he’s still anxious. There, complications arise when Tony Danza as big-time gambler Tommy Korman spies Betsy, who reminds him of his late wife, who succumbed to skin cancer from baking in the sun too much. His song “Out of the Sun” derives laughs from grim regrets. Danza, whose fame dates back to his TV show “Taxi,” is superb here. Although the character he plays is a dishonest manipulator, Danza manages to be eminently likable as a performer with his endearing audience appeal.

Korman schemes to take Betsy away from Jack by luring him into a high stakes poker came, from which he emerges owing $58,000 that he can’t possibly pay. It turns out that it is either broken kneecaps or injured balls, or convincing Betsy to spend a weekend with Korman. Naturally, this doesn’t sit well with Betsy, but anger propels her to accept the invitation to spend the weekend in Hawaii with the devious Korman, and also provides for an exotic location shift.

All this is the set-up for an avalanche of musical comedy elaboration, including Las Vegas showgirls, the very amusing Catherine Ricafort as the steamy Mahi assigned in Hawaii to detour Jack by getting him to do “Fricki-Fricki” with her. Also, I have seen many a striptease specialty in my day, but never one in which a dancer (Katie Weber as Saphire de la Tour) strums a harp with her breasts.

There are also such treats as flying Elvis imitators, skydiving, a visit to the shrine of disappointed mothers (Nancy Opel again), funny business at an airport counter, elaborate scenic movement, an elevator taking characters up from and under the stage, plus various surprises sprinkled throughout. The songs, while not great, entertainingly service the show. An assortment of supporting cast members, including Matthew Saldivar as Korman’s sidekick Johnny Sandwich, add to the pleasure and overall comic tone.
