Looks like Australia officially divorced from the crown in 1986, so we're just coming around to discovering this, but I was in Britain in the 60's as well as other family in England/Scotland and at the time there was a huge distinction between being English and British, British being all else besides within the Commonwealth, and not always a flattering distinction there, but better here, British cars/bikes, British Invasion ;[]
Even more confusing, while the Isles remained British, actual Britons would look more like this.
