Joao Da Ponte who was in my year has apparently passed away. I have only just discovered how important a figure his father Bruno was, this obit is where I learned that Joao had died – https://www.counterfire.org/articles/opinion/20064-obituary-bruno-da-ponte-1932-2018
Joao and I went to see Status Quo in about 1972 at the Empire theatre, walked home to Morningside to fried eggs at 3am. He was laid back and a really good friend who kept me honest. He had a younger brother Jose who also attended the school.

Editors note – The brothers attended the Royal High School between 1970 and 1974 then returned to Portugal as described in the linked obituary.
