At midday on a gray Jan. 30, 1969, as Londoners were heading out to lunch, the Beatles were heading to the roof of their Apple Records headquarters on Savile Row.
For 42 minutes, the quartet, aided by keyboardist Billy Preston, ripped through nine takes of five songs: "Get Back," "Don't Let Me Down," "I've Got a Feeling," "One After 909" and "Dig a Pony."
But the writing was on the crumbling wall. The band would soon fracture, and members launched their solo careers. In late 1970, Paul McCartney sued his former bandmates, bringing the Beatles to an end.

The Beatles and director Peter Jackson are collaborating on a new film about the sessions that produced the group’s final album, they said Wednesday.
The as-yet-untitled documentary is to be based on 55 hours of unreleased footage of the Beatles in the studio, shot 50 years ago this month, as they recorded the album "Let It Be." A release date is not set.
The announcement came on the 50th anniversary Wednesday of the rooftop concert, when John Lennon, Paul McCartney, George Harrison and Ringo Starr performed together public for the last time.
