At the end when Frankie is performing solo with the single drummer, the drummer's hair is neatly combed. However, during a side view, the drummer has a cowlick over one eye. which is gone when a frontal view is again shown.
During the opening barbershop scene, the shaving cream on Christopher Walken's face varies from shot to shot. The soap above his lip appears and disappears and then comes back.

At the Ohio state fair the state police arrest the group for not paying a hotel bill. That's a civil offense not a crime that the police can arrest people for. It's a local matter, not even something state police would investigate.
When the characters are arrested, the sign outside the police station reads "Ohio State Police". Ohio has a Highway Patrol, but no state police.
The Ohio State Highway Patrol would not be involved in a dispute over unpaid hotel bills. That would be handled by the county sheriff.
In the sound studio, looking into the sound booth, a character throws up a stack of papers, and some land inside the performance area. There should have been a window for them to bounce off of.
When Frankie sings "Can't Take My Eyes Off of You" for the first time at the Roostertail (1967 real life, 1980 movie), over his left shoulder is a white haired musician. This man is also in the 1990 Rock and Roll Hall of Fame band (guitarist wearing hat), but hasn't aged.

When Vincent Piazza takes off his guitar, he doesn't hold it by the neck and lift the strap over his head. Rather, he holds it by the body with his right hand and lifts the strap over his head with his left. When he puts it on, he dangles the guitar by the strap and puts the strap over his head. When putting it on or taking it off, a real guitarist always holds the guitar with his left hand by the neck and handles the strap with his right. Clearly, Vincent Piazza had never held a guitar in his hands before this film.
When the film begins in 1951, someone mentions Topo Gigio, a puppet that first appeared on Italian television in 1959 and was brought to American audiences in 1962 on The Ed Sullivan Show (1948). This goof may be an allusion to the coincidence that Topo Gigio and The Four Seasons both made their Ed Sullivan debut in the installment The Four Seasons, Peggy Lee, Anthony Newley, Jose Greco, Joey Forman, George Matson, Dominique, Alan Gale, Topo Gigio (1962).
When performing "Walk Like A Man" on American Bandstand (1952), the band is called Frankie Valli And The Four Seasons. The name changed in 1970 after Tommy DeVito and Nick Massi left the band.

When Nick Massi plays a Hammond organ (probably a C-3 or RT-3) in the church, it makes the sound of a pipe or cathedral organ.

Since the late 1800s, the Ohio State Fair is held in Columbus, not Cleveland.
After the group has been thrown out of the Four Seasons bowling alley, a motel is shown next to the bowling alley. In reality, there was never a motel next to the bowling alley, which was on W. Chestnut Street in Union, NJ. Today it is the site of a Costco.
