Paul McCartney and John Lennon, December 17, 1961, by Albert Marrion, via beatlesource.
Albert Marrion recalls “This photo session was done for [Brian] Epstein as a friendly gesture against the wishes of my partner… I took about thirty photographs…but discarded all but sixteen negatives because many showed Lennon and McCartney acting up and spoiling the pose. No doubt, those negatives should have been kept, looking back.”
Wow. Just wow.
