From the video description:
...from a documentary entitled 'Music!', made by Britain's National Music Council to examine the country's burgeoning music scene. The filmmakers were undoubtedly thrilled to be allowed access to a Beatles session in Abbey Road's Studio 2, as the group ran through early takes of "Hey Jude." The date is 30 July 1968 and we find Paul, John and Ringo on piano, acoustic guitar and drums respectively. George spends most of the session in the control room with producer George Martin and engineer Ken Scott.
