Was the first part an ecological comment - bucolic, green and pleasant land ruined by belching chimneys and dark satanic mills?
Was the NHS stuff a clever way to support it? - Who'd dare ruin it now when it has so clearly been identified as a national iconic institution in front of the WHOLE world?
Was it primarily a celebration of mediocrity? Pop culture exposed in all its chavvy crashness?
Or a relaxed, fun take on modern Britishness?
