The years don't match plums , i left Ruislip for Wales when i was 20 in 1977 , so my visits were between 73 and 77 . My brothers and sisters were born between 62 and 72 . Not sure where my older sister was born , but she was born in 54 , and may have been there . I was born in Catterick army hospital in 57 , so i am not even a Londoner really . Got lots of family around there still though , so you may have bumped into one of them .
It was a good hospital though , got my nose reset and a few other broken bones sorted there too .
