The Beatles, along with guest keyboardist Billy Preston, gave their last live performance on January 30th, 1969, on the roof of the Apple building, at 3 Savile Row. It would become the climax of their documentary film “Let It Be” (1970). The show was recorded onto two eight-track machines in the basement of Apple, by producer George Martin, engineer Glyn Johns and sound recordist Alan Parsons.
