As was the case with They Shall Not Grow Old, which found Jackson reviving a trove of archival World War I footage, the Lord of the Rings filmmaker is mining 55 hours of unreleased footage of the band, using restoration techniques to render it in modern quality. The footage was originally intended for Michael Lindsay-Hogg’s 1970 documentary Let it Be.

This weekend marked the anniversary of The Beatles’ first U.S. concert, the Washington Post has an oral history:

I never was a screamer. It was all about the music for me. The concert started with some warm-up groups, and I was relieved because I had heard about the screaming that went on in England. And I thought: Nobody’s screaming. This is going to be nice; we’re going to be able to hear them. (Laughs.) When they started playing, you couldn’t hear a thing. It was unbelievably loud, like white noise. I remember the policeman near me stuck bullets in his ears.
