You remember the story the citizens were sold but not the vote requirement seems odd. From a minimum of research, it seems there was no vote to join the EU, which did not exist at the time (1973) of the European Communities project with common currency and the rest. But in 1975 they had a referendum to stay and decided they would with a 67% Yes.
