It has been 60 years since The Beatles first set foot on U.S. soil, bringing their revolutionary music across the Atlantic from their native England. The Fab Four – John Lennon, Paul McCartney, Ringo Starr and George Harrison – were well on their way to becoming one of the greatest rock bands of all time.

“We want the Beatles, we want the Beatles,” chanted fans when the foursome arrived in New York in 1964.

The new documentary “Beatles ’64,” arriving on Disney+ November 29, offers a behind-the-scenes look at the band’s early days of stardom and their historic first visit to America.

McCartney attended the film’s premiere in New York on Sunday and was joined by musicians including James Taylor, Elvis Costello, Steven Van Zandt, Tim McGraw and Faith Hill.

“They somehow took themselves and each other to a level that no one expected,” said “Beatles ’64” producer Martin Scorsese of the band’s meteoric rise.

He also recalled the snobbery leading up to their visit.

“I will never forget that. I remember seeing a newspaper the weekend before she arrived where she made fun of her hair and basically said, ‘Oh yeah, let’s see what you get when you get here,'” he told “Nightline.” “You know, that was the attitude. And suddenly it was a revolution.”

In retrospect, this radical change seems inevitable, but the trip to New York was a risk for the four of them.

“The year is 1964, Beatlemania has been going on for a few months. They didn’t know what to expect in New York and thought maybe no one would pick them up at the airport,” “Beatles ’64” director David Tedeschi told Nightline. “They’re so happy, content and joyful about what’s going on happened – it’s a dream for them.”

Despite the incredible reception at New York’s John F. Kennedy International Airport on February 7, luxurious accommodations at the city’s Plaza Hotel and her legendary introduction to more than 73 million Americans during her appearance on “The Ed Sullivan Show” on February 9, February The band wasn’t received warmly everywhere.

“There’s a scene in the film, it’s a party at the British embassy in their honor and they’re mistreated by the staff because the embassy staff think they’re inferior,” Tedeschi said. “I can’t quote the film exactly because it’s not suitable for television, but Paul has a nice reaction, saying: Deep down we knew we couldn’t care less.”

According to the director, the band’s drummer also had an unexpected encounter with a blade at the embassy.

“Someone walked up to Ringo and cut off some of his hair,” Tedeschi said.

The director recalled that they weren’t sure if they could get surviving Beatles McCartney and Starr to give interviews for the documentary.

“We did everything we could to attract them. And Paul had this wonderful photo exhibition in Brooklyn where he himself reviewed 1964. All photos are from 1964 and I think he had something else to say. So we filmed him exhibiting the photo.”

In this interview, featured in the documentary, McCartney reflected on why he and his bandmates were so beloved by Americans.

“When we came, it was pretty soon after Kennedy was assassinated,” said the 82-year-old, who sang and played bass in the band. “Maybe America needed something like The Beatles to pull us out of its grief.”

Tedeschi hopes the documentary leaves people feeling a certain way.

“The experience of listening to music and how joyful it is and how it brings out our humanity,” he said. “I think the Beatles accomplished something more than anyone else.”
