"Life is what happens while you are busy making other plans." - John Lennon
The original concept for the film project called for the documentary to end with a live show, the first live public performance by the band since the end of their last tour, on August 29, 1966, at Candlestick Park in San Francisco. However, agreeing on a format for the live show proved problematic. Paul McCartney suggested playing a small club, like the Beatles had in the early days. John Lennon suggested an overseas location such as Africa (although he also expressed a sarcastic desire to perform the show in an asylum). Ringo Starr held out for staying home in England. George Harrison showed little enthusiasm for any live performance at all.
After failing to agree on any other venue, the band settled for an unannounced concert atop their own building, Apple's headquarters in Savile Row near Piccadilly Circus. The Beatles, performed on January 30, 1969 with some rather surprised Londoners near the Apple headquarters as the music blasts out from the roof. The performance and the film close with the police arriving and shutting the concert down. The rooftop concert has been a popular bootleg ever since, and was to be the final public performance by the Beatles.
