A strange sound takes up part of a track on the album “Love,” a compilation and remix of Beatles songs produced by Sir George Martin and his son, Giles, for a Cirque de Soleil production called “Love.” It resembles a hive of angry bees, or jet engines before clarifying itself into a solid wall of screams. Those screams are coming from thousands of hysterical adolescent girls shrieking their hearts out at a Beatles concert. The girls, and objects of their frenzy, largely swept away the fifties and ushered in the sixties, post-JFK’s assassination.

I was 12 years old on Feb. 9, 1964, when the Beatles first appeared on “The Ed Sullivan Show,” a Sunday night staple in American homes. When Sullivan shouted, “Ladies and Gentlemen, The Beatles!” and the four of them appeared in their matching outfits, mop-top haircuts, and cheeky grins, my interior wiring changed and I thought, they belong to us. I didn’t fully understand the impact they would have, but I knew things had changed.

Director Ron Howard’s documentary, “The Beatles: Eight Days a Week - The Touring Years” is a great movie for Boomers and everyone else. It begins with footage of four young Beatles playing in The Cavern Club in Liverpool and in the Reeperbahn red-light district in Hamburg, Germany and ends shortly after their last stadium concert at Candlestick Park in San Francisco on Aug. 29, 1966. Howard (Opie in “The Andy Griffith Show”) is one of ‘us’, too, born in 1954. He centers on the bond the four shared — a musical brotherhood, really — and how that served them well in the crazy days to come.

Viewers are also aware of one of the most successful marketing strategies in pop history, when the Beatles’ manager, Brian Epstein, dressed them in identical suits and cut them loose on the world with their wit and charm. Celebrities with stories about their personal Beatles experiences appear throughout the film, among them African-American historian Dr. Kitty Oliver, who attended a desegregated Beatles concert in Jacksonville, Florida in 1964, because the Beatles refused to play to segregated audiences.

Using historical concert material as well as stills and bootleg material from the period, Howard shows how, as the Beatles began to play huge stadiums, they began to lose control of their situation. They couldn’t hear one another over the screams, and Ringo was forced to watch John and Paul’s movements to figure out the beat. As time and the press conferences and tours continue, the Beatles’ faces morph from giddy lads to world-weary musicians. After Candlestick Park, when they were hauled away in something resembling a meat wagon, the Beatles stopped touring and retreated into the studio. In less than a year, they released the amazing and music-changing “Sergeant Pepper’s Lonely Hearts Club Band.”
