There are several more videos dating from the early 60s on You Tube. They were uploaded by John Sooklaris who digitised his father's old 8mm films that were shot during visits home to Crete from the US where the family had settled.
Sooklaris has uploaded 90+ videos many of which are more recent events of the family's life in the US but there are at least 12 shot in Crete in 1961.
