I am re-posting this simply as a music video. Mary liked it but didn't get to see the whole thing.
From the video description:
"The longest version of 'You Know My Name' I found, coupled with more or less rare footage from the Beatles. Recorded while 'Sgt. Pepper', released in 1970. After McCartney, Evans and Lennon added some extra vocals in 1969, Lennon planed to release (with '...Mary Jane') it as a Plastic Ono single (heavily edited by himself), but the other Beatles prevented it. Even on Anthology there are some parts of the song missing."
