If Clapham Town, Clapham North, and Clapham South are the public ones,
then where was Clapham Common?
There are only 3 tube stations in clapham as far as I know

I think you misread what Mark wrote - he said "Camden Town", not
"Clapham Town"! Clapham Common did indeed have a deep-level shelter
built, you can see the tower for it still, and apparently it was used as
accommodation for the hordes who came to the Festival of Britain in
1951, and then for those who came over on the Empire Windrush, and its
successors.
