During the course of filming the documentary Let It Be, The Beatles performed their now-legendary rooftop performance atop the headquarters of Apple Records. The performance was unannounced, with the group performing "Get Back," "Don't Let Me Down," "I've Got a Feeling," "One After 909," and "Dig a Pony."

The London police eventually made their way to the roof to try and bring the show to a close (the show was disrupting businesses' lunch hours). During the course of the show, the band ad-libbed lyrics on the spot, much to a positive reaction of London lunchgoers on the streets below.
