July 22, 1967 - Why is Magic Alex with them in the last photo? He traveled to Greece on July 20 with Ringo and George. Did he meet John and Paul at the airport when they arrived? (Surely that is the answer)
My other observation is that I always thought all four Beatles and their partners went on this trip to Greece in July of 1967. However, Maureen doesn't appear in any of the photos. She was pretty far along in her pregnancy at this time, so that might have been why she didn't come along. Such a shame that she missed out..
