Below is an interview with Brian Epstein about his first encounter with The Beatles on November 9th, 1961, followed by the band playing One After 909 during the rooftop concert scene in Let It Be (released in 1970, 9 years after Epstein met them at the Cavern Club). The Let It Be film may be scheduled for DVD/Blu-ray release in 2013. It's interesting to see how much the culture, and The Beatles themselves, changed in those nine years.
There is new documentary film in the works about Beatles secretary Freda Kelly. The film reached its initial pledge amount today, November 9th. You can learn about it (and contribute to the project on Kickstarter) here. John Lennon portrait by Richard Avedon from MOMA here.
