Nothing to do with the article, but I liked looking at the culture, at the time, in the film. Like the old man in the trench coat and pipe, that walks onto the roof across the way during the second take of "Get Back". You see him again during the song "Dig a Pony" - I guess he liked the Beatles, I wouldn't have guessed.
The interviews with people on the street during the performance were funny. I got the feeling that the interviewer was looking for older people and trying to get them to say it was a noisy nuisance. One of the first people shown was an older woman talking about how lovely it was to hear music on her way home from work.
