Look up there, on the rooftop. This is the end, but also the beginning. The surreal launch pad to The Beatles musical time machine. Get Back brings it all home, and takes us along for the ride. With a fantastic explosion of energy and light, the 60's in all their nostalgic beauty blended with the dance styles "house" and "jacking".

The crashing guitar chord from "A Hard Day's Night" announces a new era and the bombastic pulse of an unrelenting drumbeat fast-forwards the action to The Beatles' farewll concert on the rooftop of their office in central London. As a section of the stage rises, carrying a bandstand and Sgt. Pepper himself, another lift carries four "nowhere men." Projectors cast computer-generated silhouettes of the Beatles onto scrims that drop down from the ceiling. Then an explosion of energy, light and color burst onto the stage powered by The Beatles' rock anthem, "Get Back," hits hard, whirling us back to a time of birth and rebuilding. The scrims fall away. Four acrobats dressed as nurses soar up toward the catwalks, twirling, and four couples bungee into the air and then separate, bouncing past one another in midflight. The lights go crazy; the crowd from the 1965 Beatles concert at the Hollywood Bowl screams. Nostalgia of the 1960s is juxtaposed with newfangled dance styles -- "House" and "Jacking" -- and an unusual bungee tête-a-tête, as the celebration barrels toward an unsuspecting conclusion.

"Get Back" opens with George Harrison's memorable thrum from "A Hard Day's Night" and Ringo Starr's drum prologue from "The End," catches sight of an overpassing jet from "Back in the U.S.S.R.," pulls in part of the audience's expectant murmur from "Sgt. Pepper's Lonely Hearts Club Band" and borrows a bit of the orchestral swell from "A Day in the Life," landing on John Lennon's "Glass Onion."
